The first study has been done on controlling the Permanent Magnets Synchronous Machine (PMSM) by using field oriented control technique using a speed sensor to detect the rotor position of the motor. After we present the theory of sliding mode control .We can see from the simulation results that the second proposed control system (SMC), is a robust nonlinear time optimal controller, that's will be more explained in the appendix.

Standalone photovoltaic systems are widely used in remote areas after development of photovoltaic cell industry in recent years. The output characteristics of photovoltaic arrays are nonlinear and change with the cell's temperature and solar radiation. Since they cannot ensure that the operating point will match the maximum power point for all radiation and temperature conditions. Maximum Power Point Trackers (MPPT) systems are essential devices employed to maximize the power flow from a photovoltaic module (or array) to a load. In most of applications, the MPPT is composed by a DC-DC converter interposed between the referred photovoltaic module and load. The DC-DC Boost converter is proposed in this paper. A photovoltaic system has been modeled and analyzed using Matlab/Simulink software. The simulation was compared with and without MPPT. The results validate that MPPT significantly increased the efficiency and performance of the photovoltaic system compared to the system without MPPT. Fig. 4: Plot of voltage, current, power Output of PV panel without MPPT.

Research paper thumbnail of Neuro-Fuzzy Control of an Input Output Linearization of a Permanent Magnet Synchronous Machine fed by a Three Levels Inverter

It permits decoupling and linearizing the system without taking into accounts the flux orientation. The nonlinear control (NLC) applied to the PMSM decompose the system into two mono variable, linear and independent subsystems. The neuro-fuzzy control permits to the speed and the I d current control is carried out by neuro-fuzzy regulators (ANFIS). The analysis of the results obtained by this type of nonlinear regulator shows the robustness characteristic with respect to the load perturbations and the parametric variations. A qualitative analysis of the evolution of the principal variables describing the behaviour of the global system (PMSM-Inverter (PWM)-Control) is developed by several tests of digital simulation in last stage.

The sliding mode control (SMC) is used to achieve robust performance against parameter variations and external disturbances. The problem with this conventional controller is that it has large chattering on the torque and the drive is very noisy. In order to reduce a torque ripple, the sign function is used. The proposed algorithm was simulated by Matlab/Simulink software and simulation results show that the performance of the control scheme is robust and the chattering problem is solved.

However, the output power induced in the photovoltaic modules is influenced by an intensity of solar cell radiation, temperature of the solar cells. Therefore, to maximize the efficiency of the renewable energy system, it is necessary to track the maximum power point of the input source. In this paper, a new maximum power point tracker (MPPT) using Perturb & Observe algorithim is proposed to improve energy conversion efficiency. Maximum power point tracking is an important function in all photovoltaic (PV) power systems. The simulation results show that the proposed MPPT control can avoid tracking deviation and result in improved performance in both dynamic response and steady-state.
