Design of Adaptive Fuzzy Controllers for Warship Weapon Control Systems

Based on the common characteristics of most fuzzy systems in application, an adaptive fuzzy controller is proposed by combining T-S fuzzy controller with PID controller in this paper. The interpolation model of typical adaptive fuzzy controller is deduced, which can be used to develop a precise real-time control algorithm in practical use. Using the passivity theorem, the sufficient conditions of the IO stable closed-loop systems in which adaptive fuzzy controllers applied to several typical control plants are obtained. The optimal design method of adaptive fuzzy controllers is discussed in detail by means of genetic algorithms (GAs). The proposed methods have been applied in designing a warship weapon control system, and the simulation results show that these methods are effective
