一种新型控制器的设计方案和仿真研究

通过对系统状态变量的运动规律做出某些假设,构建了一种基于经典力学运动方程的状态观测器,这种观测器能精确估计被控对象的位置,速度和加速度,而无需知道被控对象的数学模型。在经典力学运动方程的基础上,设计了一种新型控制器,这种新型控制器通过系统的运动位置,速度和加速度的负反馈作用,把原被控对象的输出轨迹引导控制到期望的系统输出轨迹,它能够有效高系统的控制品质和鲁棒性能。同时本文对利用Matlab软件仿真进行了分析,对仿真步长,仿真算法的选择总结了一些经验和建议。

Design Scheme and Simulation Study of Novel Controller

By analyzing the information and motion regularity of system, a state observer based on classical dynamics was constructed, and the state observer can perfectly estimate the position, velocity and acceleration of output for the controlled plant without model of the controlled plant. A novel controller was designed on the basic of classical dynamics, and the controller can make that the output locus of the controlled plant is controlled, and the desired output locus can also be obtained, which can improve performances and qualities of control system, and some suggestions about the selection of simulation step and algorithm were given by applying Matlab software.
