Computer simulation research of double-loop speed control system based on Simulink

Double-loop speed control system is widely used at present. The cascade control using current regulator and speed regulator is realized, which can nearly approach the ideal start-up process. The system is designed on the principle of quickness, accuracy and stableness, and the project design procedures are adopted to build a dynamic mathematical model. Simulink is used to simulate the system, and the result offers a further proofs for the advantages of the system's start process.
