探究连续切换线性参数变化(LPV)系统的鲁棒H_∞滤波问题.对于整个参数变化空间,传统方法是设计单一LPV滤波器,具有较大的保守性.为此,利用多参数依赖Lyapunov函数设计了切换LPV系统的多参数依赖鲁棒H_∞滤波器,以降低设计的保守性.考虑了平均驻留时间切换逻辑,所设计的鲁棒H_∞滤波器能够确保滤波误差系统指数稳定且具有一定的H_∞扰动抑制水平.数值仿真实例验证了所提出方法的有效性. In order to solve the problem of robust H_∞filtering for continuous switched Linear Parameter Change (LPV) systems, the traditional method is to design a single LPV filter with large conservativeness for the entire parameter change space.Thus, with the multi-parameter dependent Lyapunov function design In order to reduce the conservativeness of the design, a switched multi-parameter robust H_∞filter with LPV system is considered.Analyzing the average dwell time switching logic, the designed robust H_∞filter ensures the exponential stability of the filtering error system with a certain degree of stability The H_∞ disturbance rejection level is validated by numerical simulation examples.
