The robust adaptive dynamic surface controller design for BTT missile

摘要

A RBF network based adaptive dynamic surface controller was developed for a class of uncertain MIMO pure-feedback systems. Because of the uncertainty of the i-th subsystem is depends on the state of the previous i+1 subsystems, RBF network was introduced to compensate the uncertainty on-line in order to reduce the controlling conservation, A second order sliding mode filter was introduced to produced the derivate of virtual control signal in design proceed, this resolved the ‘term explode’ that existed in conventional backstepping design, and made the controller more natty and easier to implement. At last, an adaptive dynamic surface controller was designed for a nonlinear BTT missile dynamic and simulation result was demonstrated the control system has good performance.
