Aim To study the application of fuzzy control in guidance system. Methods Using an improved fuzzy control method, the rolling stabilizing system of the long range anti tank missile was designed. The control effects of fuzzy control method on the rolling channel of the missile were studied by simulation. Results The fuzzy control in the rolling stabilizing system of the long range anti tank missile was used for the first time in China and rather good control effects were obtained. It has a high precision, a short transition course and a rather good robustness to the change of the parameter and the structure. Conclusion The method without “zero” fuzzy aggregate of inputs used in this paper is important to resolving the steadiness of the rolling stabilizing system with fuzzy control. This result can be used to the rolling stabilizing system of an extensive kind of flight vehicles and other stabilizing system.
