Abstract

The invention relates to a fine anti-interference tracking controller of a flexible hypersonic vehicle. A method for constructing the fine anti-interference tracking controller comprises the following steps of: (1) building a longitudinal model of the flexible hypersonic vehicle; (2) building a multisource interference system model of the flexible hypersonic vehicle based on the longitudinal model in the step (1): firstly, building a control-oriented nominal model; then regarding an elastic mode as interference and building an elastic mode interference model; and finally, building a multisource interference system model by combining the above two models and considering measurement errors, parameter uncertainty, external interference, etc.; (3) designing a nonlinear disturbance observer to estimate the elastic mode interference based on the multisource interference system model in the step (2); and (4) constructing the fine anti-interference dynamic reverse composite tracking controller based on the nonlinear disturbance observer in the step (3). The fine anti-interference tracking controller has the advantages of high anti-interference performance, rapid tracking speed, high control accuracy, etc., and applies to high accuracy tracking control of the height and the speed of the flexible hypersonic vehicle.

Description

technical field [0001] The invention relates to a fine anti-jamming tracking controller of a flexible hypersonic vehicle, which is mainly applied to the speed and height tracking control of the flexible hypersonic vehicle. Background technique [0002] Due to the high application value of hypersonic vehicles, all countries are scrambling to study hypersonic vehicles at present, and the configuration of their waveriders is easy to cause elastic deformation; therefore, the control of flexible hypersonic vehicles has become a hot issue in recent years . [0003] However, the control of flexible hypersonic vehicles is facing great technical challenges. First of all, the aircraft system has the characteristics of strong nonlinearity, strong coupling, and fast time-varying, so the model based on the mechanism is usually very complicated, and the existing nonlinear control methods cannot be directly applied to the flight control design; secondly, the flight span of the aircraft is...
