Abstract

The invention discloses a method for designing a discrete gain scheduling controller of a multi-balance-point saturation switching system, and relates to a method for designing a gain scheduling controller in the control field. The invention further relates to a method for controlling a BTT guided missile. The method aims at solving the problem that balance points, obtained through conversion of a design signal tracking controller, of subsystems of a practical system are not all the same. According to the method, the multi-balance-point linear switching system is built with the parameter Lyapunov equation method and the ellipsoid invariant set theory according to state vectors of the selected system, and the discrete gain scheduling controller of the multi-balance-point saturation linear switching system under a switch path related to time is designed. The method is suitable for designing the discrete gain scheduling controller of the multi-balance-point saturation switching system.

Description

technical field [0001] The invention relates to a gain scheduling control method in the control field, and also relates to a BTT missile control method. Background technique [0002] Many systems in real life show switching characteristics, that is, the whole system presents different modes among several different subsystems according to the change of environmental factors. The most obvious examples are trains, automobiles and other motor vehicles in their Speed ​​adjustment during travel and control objects that contain links such as saturation and hysteresis. In general, a typical switched system is composed of some continuous subsystems or discrete subsystems and a switching law. The progress of the entire switching system is controlled by a switching law, which is usually also called a switching law, a switching signal, or a switching function, and is generally a piecewise constant function that depends on time or system state or both. As a control idea, "switching" ha...
