Simulation on parallel drive system of double switched reluctance machines based on sliding mode controllers

The paper presented a control scheme for parallel drive system of double Switched Reluctance machines. The sliding mode control algorithm is adopted in the main controller for closed-loop rotor speed control of main machine. The sliding mode control algorithm is also adopted in the subordinate controller for synchronized rotor speed and loads equilibrium distribution between main machine and subordinate machine. The given rotor speed and the actual rotor speed of the main machine are the input parameters of the main VSS controller. The duty ratio of pulse width modulation signal of the main VSS controller can be gained by the sliding mode control algorithm. The actual rotor speed of the main machine, the actual rotor speed of the subordinate machine, 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 are the input parameters of the subordinate VSS controller. The increment of the duty ratio of pulse width modulation signal of the subordinate VSS controller can be gained by the VSS control algorithm. The nonlinear simulation results of the system based on MATLAB-Simulink show that the advanced scheme is satisfied with synchronized rotor speed and loads equilibrium distribution between main machine and subordinate machine.
