A ROBUST CONTROL OF PM SYNCHRONOUS MOTOR USING ACCELERATING TORQUE FEEDBACK

A robust control technique is ptesented for a high performance control of a permanent-magnet(PM) synchronous motor In order to deal with the internal and external disturbances of a PM synchronous moioi drive system, a new feedback control structure is proposed Since the dynamic behavior of the PM synchronous motor drive system is mainly concerned with the difference between the electro-magnetically developed toique and the load torque which generally referred to as an accelerating torque, the estimation and control techniques of this torque are introduced The simulations and experiments are carried out for the DSP-based PM synchronous motor drive system and the results well demonstrate the effectiveness of the proposed control technique.
