摘要
本文针对一类非线性不确定系统,提出了基于多项式平方和(Sum of squares,SOS)方法的一种设计可靠保性能控制器的新方法,考虑执行器故障的前提下,利用Lyapunov理论和SOS理论,设计了可靠保性能控制器。仿真结果验证了基于SOS方法的可靠保性能控制器在非线性和不确定性条件下具有良好的控制性能。
Based on polynomial sum of squares (Polynomial SOS) technique, this paper proposes a new design method of guaranteed performance control for nonlinear uncertain systems. A reliable guaranteed performance controller against actuator faults is designed using Lyapunov theory and the Polynomial SOS method. Simulation results show that the new controller based on the proposed method can provide good cost tracking control against nonlinearity and uncertainty.
