A procedure for the selection of sampling periods and weighting coefficients for the time-discrete optimal control of a time-continuous process is presented. The basis of the selection is:1 ) a linear time - discrete controller, 2 ) a limited range of the control variable, 3)an initial deviation which is given in accordance with the practical requirement to the control system. The performance index of the system is expressed in a time --continuous, quadratic, deviation loss function and a similar...

A procedure for the selection of sampling periods and weighting coefficients for the time-discrete optimal control of a time-continuous process is presented. The basis of the selection is:1 ) a linear time - discrete controller, 2 ) a limited range of the control variable, 3)an initial deviation which is given in accordance with the practical requirement to the control system. The performance index of the system is expressed in a time --continuous, quadratic, deviation loss function and a similar control-loss function.Controllers parameters are computed by standard LQ -methods for different sampling periods. The control weighting coefficient in the loss function is chosen so that full use of the control range is obtained, given the initial deviation. The final sampling periods and controller parameters are selected as a compromise between the deviation loss and the control loss. The procedure is especially useful when the longest possible sampling period is required.

本文提出了在连续过程的离散最优控制中选择采样周期和加权系数的一个方法。这个选择基于:1)线性的时间离散控制器;2)控制变量的范围受到限制;3)根据对系统的实际要求给定输出量的初始偏移。系统的性能则采用时间连续的二次型输出偏移损失函数以及类似的控制损失函数来表示。对不同的采样周期,利用标准的LQ方法来计算控制器,并通过选择控制损失项的加权系数,以使得对于给定的初始偏移,允许的控制范围得到充分利用。最后的采样周期则是权衡了偏移损失和控制损失的一个折衷选择。本文介绍的方法尤其适用于需要尽可能长的采样周期的情况。

This paper presents two methods for synthesizing discrete optimal regulator with disturbance inputs. Under step disturbances, the closed loop control systems synthesized by these methods have X(k) = 0 and (?)X(k) = 0 when k→∞, where X(k) is the state vector of the control system and symbol "(?)" represents the difference operator.

本文介绍两种有扰动输入的离散最优调节器综合方法,用它们综合的最优调节器能保证闭环控制系统在阶跃扰动作用下,当k→∞时X(k)=0且△X(k)=0。这里X(k)是被控系统状态的向量,符号“△”表示差分算子。
