Comparative study of PI-AW and MPC-T controllers, with feedback noise applied for speed control to a switched Reluctance Motor (SRM)

摘要

This paper presents the comparative study of controllers: Model Based Predictive Control (MPC) and Proportional Integral with Anti-Windup structure (PI-AW), applied to the speed control of a switched Reluctance Motor (SRM). The SRM physically presents noise in the measurement of the speed variable given in Revolutions Per Minute (RPM) to be controlled. The PI-AW and MPC controllers was observed the presence of steady-state error, this phenomenon is called Noise Induced Tracking Error (NITE). But when considering the presence of the T-polynomial tuned intuitively and applying the MPC-T control. It is possible to reduce this error considerably in comparison to the PI-AW control. The design of the controllers was validated through performance indices IAE, TV and Steady-State Error e_ss.
