探讨工业过程中包含单个右半平面极点不稳定时滞对象的稳定控制,大时滞系统的优化控制设计,对不稳定加时延模型中的不稳定部分采用比例反馈,把不稳定部分的右半平面极点配置为对称的左半平面极点,然后用两次优化方法对稳定时滞过程进行优化控制设计,形成不稳定时滞对象优化控制结构,分析不稳定时滞对象控制响应的性能,最后给出仿真几种不同难控度对象的响应结果,表明系统控制结构的简单实用,改进了对大时滞(L/T≤8)不稳定对象的鲁棒控制与抗干扰能力。
In this paper, the stability control of an object with a single right-hemispherical unstable unstable time-delay and the optimal control design of a large-delay system are discussed in this paper. Proportional feedback is applied to the unstable part of the unstable plus delayed model, The semi-plane pole is configured as a symmetrical left-half pole pole. Then two optimization methods are used to optimize the control process of the steady-state delay process to form the optimal control structure of the unstable time-delay object, and analyze the performance of the control response of the unstable time-lag object. Finally, The results of simulating several kinds of objects with different controllability are given. The results show that the system control structure is simple and practical, and the robust control and anti-interference ability of unstable objects with large time delay (L / T≤8) are improved.
