摘要
Brushless DC (BLDC) drives with permanent-magnet motors are suitable as servo motors if properly controlled. Their performance can be superior to conventional DC servos if NdFeB or rare-earth cobalt magnets are used for motor excitation, and novel control techniques implemented for its servo performance. The availability of inexpensive and high-performance digital signal processors allows the implementation of a novel instantaneous torque control algorithm for BLDC drive applications. The authors present the servo performances of a BLDC drive with instantaneous torque control. To assess the quality of this controller, its performance is compared with that obtained using conventional current controllers. Details of the control strategies are also described.< >
