Abstract Aiming at the problem of jitter in speed when load changes abruptly during operation a synchronous reluctance motor and poor resistance to disturbance, an integral type sliding film variable structure control algorithm is proposed. The regulation controlled by mode, PI controls current regulation, Simulink simulation model system built, experiments are conducted. results show that, com...

Brain Tumor is an unwanted mass when cells grow abnormally. It puts pressure on certain areas of the brain which dangerously affects its functioning. For severe tumors like malignant, surgery not a good option because they do have definite boundaries and are closely attached with other healthy tissues brain. So chemotherapy preferable in this case to avoid damaging cells. The primary intention ...

Magnetic levitation (Maglev) systems are widely employed in the industry especially mechatronics for precise positioning and suspension. They inherently unstable having nonlinear models with uncertain parameters exposed to external disturbances. Therefore, high-performance robust control designs recommended these systems. An Adaptive Variable Structure Controller based on barrier function (AVSC...

The design process and complexity of existing safety controls are heavily determined by the geometrical properties environment, which affects proof convergence, scalability, performance robustness, numerical efficiency control. Hence, this brief proposes a variable structure control to isolate environment’s from structure. A super-twisting algorithm (STA) is used achieve accurate trajectory tra...
