The study suggests a new and innovative treatment option involving an exergame that utilises robotics technology to motivate and involve youngsters with autism in fine motor exercises. The study uncovers the common fine motor disabilities that young children often experience, emphasising the substantial influence on their everyday activities. The study introduces a new strategy that addresses the inherent constraints of traditional exercise methods by integrating robotics technology with therapeutic devices. The proposed intervention centres upon a robotic exoskeleton and hand that enables youngsters to do precise motor activities while receiving immediate feedback. This exergame not only tackles specific motor impairments, but it also focuses on the fine motor skills in the hands, which are associated with the visual attention of children with autism. The technology captures and analyses finger movements during workouts, allowing for real-time monitoring through a cloud-based server system. The technological approach utilises Arduino and Raspberry Pi devices that have been configured to regulate the entire operational circuit. This intelligent agent aims to revolutionise physical therapy by seamlessly integrating it with state-of-the-art robotics technology. If the mission operations are successful, the study predicts the creation of a highly advanced system that can significantly enhance the fine motor skills of youngsters with autism. This study contributes to the expanding field of assistive technologies, offering a possible solution for enhancing therapy techniques and producing favourable results in the autistic community.

This analysis requires certain amount of system modeling level. The main components of the system models are excitation system, synchronous machine and the Power System Stabilizer. The Simulink /Matlab are used as the programming tool for analyzing this system performance. Design optimization arobust PSS based on genetic algorithm (GA) approach has been improvement. A proper design is required for this power system stabilizer (PSS) performance using the particle swarm optimization (PSO) to archieve this. Then the implemented of the model and response of the dynamic system is been analyzed. The designed without PSS showed an unacceptable system response since as shown in the simulation results, system response with PSS proven to have improvements and PSS succeeding in stabilizing an unstable system. Therefore this leads to stability of the performance of the generator.

The main obstacle of conventional sliding mode control is the presence of chattering phenomenon. It is known that the large switching gain of sliding mode control is proportional to the chattering level, and normally a large switching gain is applied to handle the uncertainties. In this paper, this chattering phenomenon is significantly reduced by a newly developed algorithm. The control algorithm incorporates the adjustment of switching gain value and variation of the boundary layer to replace the discontinuous function in conventional sliding mode control. As a result, the boundary layer and the switching gain will change in the presence of uncertainties and load disturbances. The experimental results show the effectiveness of the proposed sliding mode control is superior in reducing the chattering phenomenon and handling the external load disturbances.

The asynchronous machine is well known about natural limitations fact of highly nonlinearity and complexity of motor model. In order to resolve these problems, the IFOC is applied to control the instantaneous electrical quantities such as torque and flux component. As FOC is controlling the stator current that represented by a vector, the torque component is aligned with d coordinate while the flux component is aligned with q coordinate. There are five levels of the incremental system are gradually built up to verify and testing the software module in the system. Indeed, all of system build levels are verified and successfully tested in PSIM environment.

Initially, the input scaling factors are calculated based on known motor data and symmetrical triangular membership functions have been used for standard design. Then, asymmetrical convergent peak value positions of these membership functions have been considered to improve the control performance. The simulation test is done for low, half and full rated speed response and load disturbance for full rated speed. By tuned membership functions, the results demonstrate that the robustness and the effectiveness of fuzzy logic controller for high performance of induction motor drives system is achieved.

Therefore, this paper presents a fuzzy logic (FL) control system based on FL approach for a vector controlled induction motor drives for high performance application. The analysis, design and simulation of the FL controller for vector control induction motor are carried out based on scaling factor and membership functions theory. First, the drives system was simulated with Standard Constant Parameter FL, Design Case Constant Parameter Fuzzy Logic and PI controller. Then the best performances of these controllers were compared to proposed optimized fuzzy logic controller (OFL). The OFL is done by tuning of scaling factor for the change in speed error, Gce to produce a better transient behaviour, and altering the width and moving the peak value positions of membership functions to improve control performance. The results show that the proposed OFL gives better performances in tracking performances and also load disturbances. The test is done in different operating conditions for half rated speed and full rated speed, half and full load condition. The results demonstrates the robustness and the effectiveness of OFL controller for high performance of induction motor drive system.

The design and simulation of fuzzy logic controller are considered based on design case constant parameter fuzzy logic (DCCPFL) controller. The scaling factors for DCCPFL controller are calculated based on identified motor parameter. The performance of the DCCPFL is compared with conventional PI controller. Three different parameters is tested under no-load and loaded conditions namely rotor resistance, inertia and self-inductance. From the simulation results, it is proved that the DCCPFL have better performance in term of different parameter variations and also load disturbances. Thus the DCCPFL is appropriate to replace the conventional PI for high performance of induction motor drives system.

Most of these children have difficulty with fine motor skills which typically struggle with handwriting and fine activities in their routine life such as getting dressed and controlled use of the everyday tool. Because fine motor activities encompass so many routine functions, a fine motor delay can have a measurable negative impact on a person's ability to handle daily practical tasks. This project proposed a simple fine motor exercise aid plus the game (exergame) for autistic children who discover from fine motor difficulties. The proposed exergame will be blinking randomly and user needs to bend their finger accordingly. It will notify the user, whether they bend the right finger or not. The system is realized using Arduino, which is programmed to control all the operated circuit. The feasibility studies with six autistic children were conducted and found the chi...
