A Nonlinear Control Algorithm Based on Adaptive Wavelet Net for STT Anti-ship Missile

摘要

A new nonlinear control algorithm of combining dynamic inversion, wavelet net and sliding mode control has been developed. The nonlinear dynamic theory is used to approximate linearization of the nonlinear system, the system dynamic inversion error is compensated by wavelet net which is capable of online learning. The adaptive weights adjustment rule is derived by using Lyapunov stability theory, and the system robustness is guaranteed by using sliding mode control and robustness control. The presented nonlinear control algorithm is applied to one STT missile control system. The simulation results show the proposed algorithm can eliminate the influence brought by disturbance availably, raise the precision of missile overload control system response
