The article presents a unified control system designing scheme to obtain enhanced performance for processes including integrator and dead time. A simple control structure including two controllers is proposed. Servo performance and disturbance rejection performance can be adjusted independently by introducing a desired transfer function model in the control structure. Servo controller is designed according to the direct synthesis principle and disturbance rejection controller is derived adopting the internal model control (IMC) theory. Simulations have been conducted on four kinds of integrating plants with dead time. The simulation results exhibit that noteworthy enhancement can be achieved by the presented scheme in comparation with the other methods even though there are perturbed dynamics.
本文提出了一种统一的控制系统设计方案，以提高包含积分环节和死区时间的过程的性能。提出了一种由两个控制器组成的简单控制结构。通过在控制结构中引入期望传递函数模型，可以独立调整伺服性能和抗干扰性能。根据直接综合原理设计伺服控制器，并采用内模控制（IMC）理论推导抗干扰控制器。对四种具有死区时间的积分型对象进行了仿真。仿真结果表明，即使存在扰动动态，与其他方法相比，本文提出的方案也能实现显著的性能提升。
