摘要

针对带有延时、大惯性换热器温度控制问题，设计基于扩张状态观测器（ESO）动态面控制器。换热器温度控制是非线性的、时变的和不确定的动态过程，采用扩张状态观测器不仅可以获取系统不可测状态还能实时估计系统动态；采用动态面控制律，实现对温度的精确快速跟踪。利用Lyapunov函数证明控制系统的稳定性。通过对经典PID控制方法、动态矩阵控制方法和基于扩张状态观测器的动态面控制方法进行比较，仿真结果表明基于扩张状态观测器的动态面控制方法具有更优越的控制效果和鲁棒性能，且在被控系统设定值和扰动发生变化时具有更好的动态响应性能。

Abstract

For the temperature control problem with time delay and large inertia heat exchanger

the design is based on the extended state observer (ESO) dynamic surface controller. The heat exchanger temperature control is a nonlinear

time-varying and uncertain dynamic process. Firstly

an extended state observer is designed to obtain the immeasurable state and dynamics of the system in real time. Secondly

dynamic surface control is used to achieve accurate and fast tracking of temperature. Then Lyapunov function was used to prove the stability of the control system. Finally

the simulation results show that the dynamic surface control method based on ESO has superior control effect and robust performance by compared the classical PID control method and the dynamic matrix control method. The proposed method has better dynamic response performance when the controlled system set point and disturbances change.
