摘　　要：对Stribeck摩擦力矩模型进行研究,采用模式识别方法估算速率稳定平台Stribeck摩擦力矩,结合常用电机及负载模型、传感器模型和载体扰动模型等建立速率稳定平台隔离度模型。针对速率稳定平台稳态精度高、响应速度快且稳定裕度大的要求,用频域分析法设计两种控制器,并在MATLAB/Simulink中建立稳定平台控制系统模型进行控制器设计,建立隔离度仿真模型进行仿真和验证。将两种控制器离散化,采用计算机控制,利用实际产品进行试验验证,提出了一种提高稳定平台隔离度的方法。The model of Stribeck friction torque is studied in the thesis and the value of stribeck friction torque is estimated by pattern recognition. Combining frequently used motor and load model, sensor model and vector perturbation, the model of platform disturbance rejection is expounded. In the light of high accuracy, speedy and large margin, we design two controllers by frequency analysis. The emulation model is set up in Simulink and used to process the emulation of platform disturbance rejection. The two controllers are discreted, and the disturbance rejection of production is tested by computer. On the basis of the result, the method of improving platform disturbance rejection is put forward.
