Second-order Systems Velocity Feedback Gain Control Based on PID Variable Damping Ratio Controller

摘要：

Generally, in order to improve dynamic performance, second-order systems generally decrease oscillation and overshoot of output response by increasing equivalent damping ratio with velocity feedback. But output response will be dull and systems speediness property will be worse because of damping ratios increment Variable damping ratio control by fuzzy adaptive PID may adjust systems damping ratio in real-time on line on the base of output responses different phases, so improve systems dynamic property. It is proposed variable damping though establishing PID s three parameters fuzzy logic control rules based on property of PID control and fuzzy logic control. Simulation results verify that the method is feasible, dynamic propertys improvement is prominent, and disturbance rejection property and robust is excellent.
