The Research Of The Minimum No Ripple Control System Simulation Based On The Electromagnetic Speed Motor

Based on the classical control theory, this paper proposes an adjustable speed motor control model with minimum ripple effect. This feasibility study was conducted and simulated in Matlab using three typical input signals : the unit step, unit speed and acceleration. The simulation results shown that, the minimum ripple controller could ensure the speed of the electromagnetic speed control motor followed the expected speed in the shortest sampling cycle, to achieve the steady-state error of the system to zero. However, it only follows a particular input signal and therefore when the input signals vary, the controllers need to be calibrated separately to follow the signals, hence, with an electromagnetic adjustable speed motor, it is feasible to control a thin coal seam electrical traction shearer with minimum ripple effect.
