摘　　要：为了满足摩擦力扰动较大且扰动非线性明显的控制系统对良好控制品质的要求,文章对传统PID作了改进,提出了一种平滑微分变积分参数PID算法。理论和仿真研究以及在组合导航仿真实验台中的实际调试,证明该算法能兼顾大偏差下的动态品质和稳态精度,具备理想的控制效果。There are some control systems that have severe nonlinear friction disturbance. In order to meet their expectation of good control quality, a modified PID algorithm is designed, which includes special smoothing differential algorithm and variable integral parameter algorithm. It can give attention to both the dynamic quality under large error and the steddy state precision. Not only the theory analysis and simulations, but also the practical application at simulating table for integrated navigation system prove this algorithm is effective.
