Position tracking control of switched reluctance motor with adaptive linear element based on current-sharing method

A novel position tracking control strategy is proposed for switched reluctance motor (SRM) in this paper. The control strategy design can be divided into two steps. The first step is the position control loop design for the SRM, which is composed of proportional plus derivative (PD) controller and adaptive linear element (Adaline). The weights of the Adaline are trained with sliding-mode-learning algorithm (SMLA). The position controller has the united merits of the Adaline and sliding mode control (SMC). The second step is the inner current control loop design. The output of the position control loop is considered as the virtual reference current. The virtual reference current is divided into referenced phase current of the SRM with the proposed current-sharing method (CSM). The proposed position tracking control strategy need any model information on the SRM besides the phase number of the SRM. Simulation results certify that the proposed method not only can realize the position tracking of the SRM, but also has high control performance.
