Application of Inverse Systems Method in Guidance Systems

Using the principle of invere system method in non-linear control and based on the multi-variable identification, this paper proposes an inverse system controller for a kind of long-rallge anti-tank missile guidancr system This method diminishes the difference between the identification model and the original system,reduces the effect on fast responce of the controller caused by input constraint through alterations in the input parameters of pseudo-linear controller.Results of digital simulation has shown that guidance system designed by this method has good control effect on missiles and that the algorithm of the contoller is simple and easy to realize in engineering.
