Study of Two-Loop Speed-Regulation System based on IMC and IMC-PID

In order to solve the bad start current wave and speed overshoot of Two-Loop Speed-Regulation System, ASR and ACR are designed based on Internal Model Control (IMC) and Internal Model PID Control (IMC-PID) taking into engineering method account. Meanwhile, the simulation results show that current wave is ideal and the speed overshoot is eliminated successfully. Steady-state performance and dynamic performance are acquired. This is a new method for improving DC motor speed adjusting performance.
