工业过程的动态特性一般都可以简化成传递函数为一阶加滞后或二阶加滞后的系统(以下称低阶滞后系统)。探讨低阶滞后系统的最优控制器的设计显然是很有实际意义的,尤其是现在单片机、电脑型的智能控制器正逐步取代常规控制仪表,使得工业过程控制中实现最优控制成为切实可行,因此迫切需要研究提供一套实用的设计方法和程序,使最优控制理论得以走向实际应用。最优控制系统的设计方法较之常规的经典控制系统的设计方法有很大差别,最优控制系统的设计完全脱离了经典控制的试凑,可以方便地籍助计算机辅助设计。本文介绍一种用 The dynamics of industrial processes can generally be reduced to systems with first-order or second-order and late-lag transfer functions (hereafter referred to as low-order lag systems). It is obviously very practical to explore the design of the optimal controller for low-order hysteresis systems. Especially now that the intelligent controllers of single-chip microcomputer and computer type are gradually replacing the conventional control instruments, it becomes feasible to realize the optimal control in industrial process control Therefore, there is an urgent need to study and provide a set of practical design methods and procedures so that the optimal control theory can be put into practical application. The design method of the optimal control system is quite different from the conventional design method of the classical control system. The design of the optimal control system is completely out of the classic control of the trial and can be easily assisted by computer-aided design. This article describes a use
