参数空间多目标数字PID控制器设计

Multi-Objective Digital PID Controller Design in Parameter Space

Haoan Wang, Levent Guvenc

摘要:

本文利用鲁棒控制的参数空间方法,提出了一种多目标数字PID控制器的设计方法。绝对稳定性首先通过找到对应于单位圆内的闭环极点的数字PID控制器增益参数空间来处理。相位裕度、增益裕度和混合灵敏度界被视为频域约束。给出了满足这些约束条件的数字PID控制器参数空间域的确定方法。所有这些区域叠加,得到一个多目标数字PID控制器增益参数空间解域。以自动驾驶汽车路径跟踪控制器设计为例,说明了该方法的有效性。

英文摘要:

This paper presents a multi-objective digital PID controller design method using the parameter space approach of robust control. Absolute stability is treated first by finding the digital PID controller gain parameter space corresponding to closed loop poles being inside the unit circle. Phase margin, gain margin and a mixed sensitivity bound are treated as frequency domain constraints. Determination of digital PID controller parameter space regions satisfying these constraints is presented. All of these regions are superimposed to obtain a multi-objective digital PID controller gain parameter space solution region. The path following controller design of an automated driving vehicle is used as an example to illustrate the method.
