Simulation on double switched reluctance machines parallel drive system with PI & VSS control

A PI & sliding mode control scheme for parallel drive system of double Switched Reluctance motors is presented in the paper. The PI control algorithm is adopted in the main controller for closed-loop rotor speed control of main motor. The sliding mode control algorithm is adopted in the subordinate controller for rotor speed synchronization and loads equilibrium distribution between main motor and subordinate motor. The given rotor speed and the actual rotor speed of the main motor are the input parameters of the main PI controller. The duty ratio of pulse width modulation signal of the main controller can be gained by the PI control algorithm. The deviation between the average values of DC bus supply current for main power converter and the average values of DC bus supply current for subordinate power converter, and the deviation between the actual rotor speed of the main motor and the subordinate motor are the input parameters of the subordinate sliding mode controller. The duty ratio of pulse width modulation signal of the subordinate sliding mode controller can be gained by the sliding mode control algorithm. The nonlinear simulation results of the four-phase 8/6 structure system prototype based on MATLAB-Simulink is given.
