Considering the uncertainties parameters and unknown dynamics of permanent-magnet synchronous motors in real applications, a composite controller strategy for electromechanical actuator is proposed in this paper. The composite strategy consists of a disturbances observer based on linear extended state observer that suppresses disturbances by feedforward compensation and a Lyapunov stability-based...
Starting control is the key problem of switch reluctant motor control. The follow-up process is as important as the starting. This paper research on this problem, using matlab to simulate the SRM model. With two phase start-up method‥Analysis of the current, torque, speed and other parameters. Achieved good result and waveform. Improved system starting ability.
