Simulation and Optimization of Parameters on DC Motor Double Closed-Loop Control System Based on Simulink

When transient performance requirement is higher in the control system and single-loop control system can not meet the requirements, we implement the multi-loop control and parameter optimization in line with the inner loop to outer loop of the order. This article takes double-loop DC motor speed control system as an example, and uses simulation optimization methodology to design of two PI regulator parameters, which make the system of dynamic and the steady-state static indexes reach the design requirements.
