Implementation of Real-Time Parameter Estimation for PMSM Using 10MHz Multisampling Deadbeat Control with Composite Vector of PWM Pulses

Advancements in semiconductor technology have enabled high-speed control in the field of power electronics. While applying deadbeat control to the control of Permanent Magnet Synchronous Motors (PMSM) is well known to provide high responsiveness, a challenge exists in its susceptibility to variations in state variables. Previous studies have demonstrated enhanced robustness through the application of 10MHz-disturbance-compensation multi-sampling deadbeat control using a high-performance controller known as the USPM controller. Furthermore, a realtime parameter estimation method based on the synthetic vector trajectory of PWM pulses using the USPM controller was proposed, confirming excellent robustness. In this study, a method to implement a parameter estimation technique with the USPM controller was verified.
