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 *** proposed composite nonlinear feedback control approach consists of two *** 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 *** this research,the genetic algorithm in line with the fuzzy logic is designed to calculate constant controller coefficients and optimize the control *** effectiveness of the proposed design is demonstrated by servo position control system and inverted pendulum system with DC motor simulation results.
