摘　　要：The objective of this research is to realize a composite nonlinear feedback control approach for a class of linear and nonlinear systems with parallel-distributed compensation along with sliding mode control technique.The proposed composite nonlinear feedback control approach consists of two parts.In a word,the first part provides the stability of the closed-loop system and the fast convergence response,as long as the second one improves transient response.In this research,the genetic algorithm in line with the fuzzy logic is designed to calculate constant controller coefficients and optimize the control effort.The effectiveness of the proposed design is demonstrated by servo position control system and inverted pendulum system with DC motor simulation results.针对一类具有平行分布补偿的线性和非线性系统,采用滑模控制技术,实现了一种复合非线性反馈控制方法。所提出的复合非线性反馈控制方法由两部分组成。第一部分给出了闭环系统的稳定性和快速收敛响应,而第二部分改进了瞬态响应。本研究设计了符合模糊逻辑的遗传算法来计算常系数和优化控制效果。通过伺服位置控制系统和倒立摆系统的仿真,验证了所提设计的有效性。
