The Rotation Speed Control of DC Servo Motor Based on Fuzzy-PI Dual Mode

Abstract:

The PID control algorithm is simple. But when it controls DC servo motor of nonlinearity, delay and strongly couple, its dynamic control performance is poor. Fuzzy control which is essentially equivalent to a nonlinear PD control has poor steady state performance. Fuzzy-PI dual-mode control simultaneously has PID control's steady-state performance and fuzzy control's dynamic performance. The step response simulation results shows that Fuzzy-PI controls rise time is 8sec and that the overshoot and steady-state error are close to 0. It has stronger anti-interference ability, higher dynamic performance and higher steady state performance.
