为了解决飞机舵机在实际使用过程中的非线性因素,建立了液压舵机伺服系统的数学模型并设计了一种双模糊控制器;该控制器利用“粗调”模糊控制器实现系统快速响应,利用“细调”模糊控制器满足系统准确性要求;运用Simulink对系统模型进行仿真;仿真结果表明,双模糊控制与PID控制、P控制相比,使系统的调节时间缩短了0.4s,受到干扰后再次稳定的时间提高了0.16s,使系统具有更好的快速性和抗干扰能力,为解决实际中的不确定使用因素提供了一种思路。
In order to solve the non-linear factors in the actual use of the aircraft steering gear, the mathematical model of the servo system of the hydraulic servo is established and a double fuzzy controller is designed. The controller realizes the system by using the “coarse tuning” fuzzy controller Fast response, use of “fine ” fuzzy controller to meet the system accuracy requirements; use Simulink to simulate the system model; simulation results show that the double fuzzy control compared with the PID control, P control, the system adjustment time is shortened 0.4s, the stability time after being disturbed increases by 0.16s, which makes the system more rapid and anti-interference ability, which provides a way of thinking for solving the uncertain factors in practice.
