Speed Control of DC Motor using Composite Nonlinear Feedback Control
- 信息技术－已发表论文 
This paper presents the design of the composite nonlinear feedback (CNF) control law for DC motor speed control. First, a linear feedback control law is designed such that the closed-loop system under this linear control law has small damping ratio. Then, a nonlinear feedback part is designed based on this linear feedback law. The nonlinear function of the nonlinear feedback part is tuned by formulating the parameter tuning problem into a minimization problem. The minimization problem is solved by Hooke-Jeeves algorithm. The well designed CNF control law results in a satisfied transient performance with small overshoot, and fast rising time and settling time.
