Design of DMC on Route Tracking

摘要:

动态矩阵控制(DMC)是模型预测控制(model predictive control)的一种典型算法,通过模型预测、在线滚动优化和反馈校正来对被控系统实施优化控制,能有效处理系统输人输出约束和抑制随机干扰。论文在碟形飞行器控制模型基础上,设计了基于DMC方法的飞行器航迹跟踪控制系统。通过选取多组参数进行仿真研究,明确了DMC方法三个主要参数在系统中的作用,并获得了较好的航迹跟踪控制效果。

Abstract:

Dynamic matrix control (DMC) is a typical control algorithm of model predictive control. Through model prediction, on-line rolling optimization and feedback rectification, the optimization of controlled system is implemented. The constraints of system input and output can be effectively handled, and random interference can be restrained. In this paper, the DMC algorithm was implied on tracking control system based on the Dishing Vehicle control system. The designed system was simulated through several parameters. The simulation results showed the three main parameters and the good performances.
