【摘要】 根据在线采集到被控对象的状态信息，应用加权递推最小二乘法进行参数估计，设计出自校正PID控制算法，把闭环极点配到希望的位置上，并给出了以实际对象为背景的仿真结果．更多还原

【Abstract】 Based on the sampling state information of the plant in line, the parameter estimation is made by the use of the weight recursive least squares and the self-tuning PID control alghthm is designed. With the placement of close-loop pole to hope side,the simulation result of practice plant is given.更多还原
