Fuzzy Logic Based Field Oriented Control Of Permanent Magnet Synchronous Motor
International Journal of Electrical Electronics and Data Communication, 2015
The present research is indicating that the Permanent magnet motor drive could become serious competitor to the induction motor drive for servo application. Further, with the evolution of permanent magnet materials and control technology, the Permanent Magnet Synchronous Motor (PMSM) has become a pronounced choice for low and mid power applications such as computer peripheral equipments, robotics, adjustable speed drives and electric vehicles due to its special features like high power density, high torque/inertia ratio, high operating efficiency, variable speed operation, reliability, and low cost etc. However, the main disadvantage of PMSM is the non-uniform variance in the developed torque. Vector controlled PMSM drive provides better dynamic response and lesser torque ripples. This paper proposes a Fuzzy logic control scheme for a PMSM drive driven by Field Oriented Control (FOC). The proposed scheme is developed in MATLAB/SIMULINK environment. Simulation results are generated for testing the performance validity of the control law.

Sensorless vector control of a Permanent magnet synchronuous motor with fuzzy logic observer
Electrical Engineering, 2005
Due to its own structural characteristics, permanent magnet synchronous linear motors have unstable motor parameters during operation due to the end effect and the inherent magnetic circuit instability. At the same time, linear motors have the characteristics of reciprocating switching motion and high-speed positioning motion in industrial applications, thus placing high demands on the controller. In order to better realize the control of the permanent magnet synchronous linear motor and simplify its structure, this paper firstly studies the linear motor body, and obtains the distribution characteristics of its air gap magnetic field, and carries out simulation analysis for the back EMF of PMSLM of its running process, then we designs a state observer based on sliding mode (SMO), replaces the traditional speed sensor, and designs a super-twisting sliding mode controller. And the double-closed loop control of the speed, and the use of high-order sliding mode control features, effectively reduce the chattering of the system, and reduce the impact of the observation error brought by the observer on the system. And the adaptive sliding mode control strategy is used to effectively suppress the influence of the boundaryless uncertainty interference on the system, and reduce the influence of the observation error brought by the observer on the system. This paper also combines the linear motor experimental platform to further verify the control scheme based on Super-twisting sliding mode non-sensing linear motor. The simulation and experimental results show that SMO has accurate speed and position tracking performance, the system's chattering is significantly reduced, the control precision is excellent, and the introduction of adaptive sliding mode controller enhances the robustness of the system.
Performance analysis of fuzzy logic controlled permanent magnet synchronous motor drive
Proceedings of IECON '95 - 21st Annual Conference on IEEE Industrial Electronics, 1995
This paper deals with the performance analysis of the field oriented control (FOC) of Permanent Magnet Synchronous Motor (PMSM) drive with a PIP (Proportional plus integral plus derivative) in dc link voltage control and fuzzy PID for speed control in closed loop operation. A mathematical model of the PMSM drive has been developed by considering each acessories of the model to analyze both the steady state and transient performances of the PMSM drive system. The current controlled inverter feeding power to the PMSM motor is powered from a PWM current controlled converter. The advantages of the integrated PMSM drive are demonstrated. The PID voltage control takes care of the constant dc link voltage to feed the inverter. The fuzzy controller provides a better response to the drive system specially in the steady state condition. The state space model developed interms of derivatives of winding currents, dc link voltage, supply currents, rotor speed, and rotor position are simulated to obtain the required information. The study also examines the effectiveness of the PMSM drive under steady state and transient conditions for different parameter variation.

In this paper, speed control and torque ripple minimization of a sensorless Permanent Magnet Brushless DC (PMBLDC) motor drive system with varying load is analyzed. Constant speed operation with minimum torque ripple during transient state is the most difficult part in the drive system. At starting condition, if the motor is started with constant DC source, the current is too high due to the absence of back EMF. Therefore the motor will start with high torque ripples. In order to eliminate the torque ripples during starting condition by limiting the starting speed of the motor with properly designed speed controller and varying DC source from zero to its rated voltage, this will improve the reliability of PMBLDC motor. Here, the speed control and torque ripple minimization of a sensorless PMBLDC motor during starting and running condition with conventional and fuzzy logic controllers are proposed. The performance parameters of a PMBLDC motor with these controllers are analyzed through MATLAB/Simulink software.

The controlling of the PMSM drive is necessary due to frequent usage in various systems. The conventional proportional-integral-derivative (PID) controller's drawbacks are overcome with fuzzy logic controller (FLC) and adopted in the PMSM drive system. In this manuscript, an efficient field-oriented control (FOC) based PMSM drive system using a fuzzy logic controller (FLC) is modeled to improve the speed and torque response of the PMSM. The PMSM drive system is modeled using abc to αβ and αβ to abc transformation, 2-level space vector pulse width modulation (SVPWM), AC to DC rectifier with an inverter, followed by PMSM drive, proportional integral (PI) controller along with FLC. The FLC's improved fuzzy rule set is adopted to provide faster speed response, less % overshoot time, and minimal steady-state error of the PMSM drive system. The simulation results of speed response, torque response, speed error, and phase currents are analyzed. The FLC-based PMSM drive is compared with the conventional PID-based PMSM drive system with better improvements in performance metrics.

FPGA-Based Fuzzy Sliding Mode Control for Sensorless PMSM Drive
CASE-The 8th IEEE International Conference on Automation Science and Engineering, pp. 172-177 , 2012
This paper presents an observer-based fuzzy sliding mode controller for sensorless Permanent Magnet Synchronous Motor (PMSM) drive based on the Field Programmable Gate Array (FPGA) technology. For enhancement of robustness, a sliding mode observer (SMO) is proposed to estimate first the current and back electromotive force (EMF), then to derive the flux angle. These estimated values together with the computed rotor speed of the motor are fed back for the control purpose in both the current loop and the speed loop. To cope with the effect of the system dynamic uncertainty and external load, a fuzzy sliding mode control (FSMC) is designed by incorporating a fuzzy inference mechanism into a sliding mode control scheme to tune the gain of the sliding term in the speed control loop. An FPGA chip is designed for implementing the current loop with vector control as well as the speed control loop. The very high speed integrated circuit-hardware description language (VHDL) is adopted to describe advantageous behaviors of the proposed control system. Integrating advantages of the sensorless technique and fuzzy sliding mode control technique into the speed controller of a PMSM drive can make its performance substantially improved and its cost effectively-reduced while improving its reliability. The validity of the proposed approach is verified through simulation results based on the Modelsim/Simulink cosimulation method.
