| 摘 要： | 神经网络控制特别适用于具有非线性和不确定性因素的系统。采用小波神经网络(WNN)对飞行仿真转台的直流伺服系统进行实时辨识,得到其逆模型。然后将这一训练后的网络作为前馈控制器与常规反馈控制器结合构成并行自适应逆控制器,控制转台跟踪指定的速度和位置轨线。仿真结果表明该方法的有效性。

| Abstract: | Neural network control is well-suited for the system with nonlinearity and uncertainty. In this paper, wavelet neural network(WNN) is used to identify the inverse model of the flight simulator. After the training, an adaptive inverse controller which is a combination of a neural network feedforward controller and a traditional feedback controller is formed to drive the simulator to track the preselected trajectories in speed and position. Simulation results verify the effectiveness of the proposed method. |
