On the application of self -adaptation and mutation domain fuzzy algorithm in the optimization of the dynamic characteristics of micro -aircraft

Adjust the gesture of small aircraft, adjust the use of permanent magnet synchronous motor (PMSM) servo control system aircraft size, different system rotation of the rudder ring installation position, etc., and the transition of the aircraft in the air encountered in the air. At the time, the traditional PI control method and fuzzy control method cannot solve the problem of slower system response and the problem of turning the system caused by it. This article proposes a fuzzy control algorithm based on model reference self -adaptation. First of all, the system's rotation inertia parameters are recognized online through the MRAS algorithm, and then the identified results are fed back to the vague algorithm of the transformation domain to obtain a real -time PI parameter change volume to achieve precise control of the servo control system. Through the simulation verification, the results indicate that the model refer to the self -adaptation domain blur control algorithm has high accuracy of the online recognition of system rotation inertia. Compared with the traditional blur control method, the dynamic characteristics of the system have been improved.
