ALGORITHM AND SIMULATION OF OPTIMAL CURRENT ANGLE CONTROL OF A SYNCHRONOUS RELUCTANCE MOTOR DRIVE

Based on the optimal current angle control concept of high performance reluctance motor, this paper develops an algorithm and a controller s tructure to implement this concept. In the proposed algorithm, the dri ve system states are categorized into transient and steady state accor ding to the comparison with the goal state, and different control stra tegies are employed for transient and steady state in order to achieve the highest performance of the synchronous reluctance motor. Extensiv e digital simulation was performed to show that this control strategy has the advantage of faster transient response and highest steady-stat e performance as well as great speed reversal and load torque disturba nce rejection capabilities.
