摘要
工程中,目标信号的加速度是很难通过目标的位置信号求取,因此,微分器的鲁棒性和高阶导数的求取至关重要,同时迅速精确地获得目标的速度和加速度对于控制系统是非常重要的。提出了基于三阶积分链式微分器的带噪声的不确定系统反馈控制设计,微分器算法有多重积分链结构,能够逼近不确定项,对系统的未知状态进行估计。仿真结果表明,微分器的反馈控制具有良好地估计和跟踪效果。
The acceleration of target signal is very difficult to obtain in the targeting location signal in engineering,therefore,robust of the differentiator and high-order derivative countdown is critical to the control system,the speed and acceleration of the target are got rapid precisely,which is very important for the control system.So it is presented in this article that is based on third-order integral chained differentiator used in the feedback control of uncertain system with noise.The algorithm of differentiator has the structure with multiple integral chains,which can approximate the uncertain item and estimates of the unknown state of the system.Simulation results show that the differential feedback control has a good estimation and tracking results.
