Parameter Estimation Method of Ultra Robust 10MHz Multi-sampling Disturbance Compensation Deadbeat Control for PMSM Drive Using USPM Controller

Recently, permanent magnet synchronous motors (PMSM) have been applied in various fields due to their advantages such as high availability and easy maintenance characteristics. Previous studies have shown that PMSM drive systems with deadbeat control method have good control accuracy but are susceptible to the parameter variations. In this paper, a PMSM drive system with 10 MHz multi-sampling disturbance-compensation deadbeat control method using an ultra high-spec USPM controller was proposed, and its ultra wide robustness was verified. Also real time parameter estimation method was proposed based on the output vector locus of PWM inverter, parameter variations of PMSM can be identified, superior robustness can be realized.
