Abstract

A constructive method for solving the linear-quadratic problem of the optimal control of a parabolic-type system with distributed parameters is proposed under the condition of the uniform estimation of the target sets. The optimality criterion takes the form of an integral quadratic estimate of the controlled state function in the spatiotemporal domain of its definition. A parameterized representation of the control inputs is given with the required accuracy within special intervals of the optimal process, where the control inputs cannot be determined using first-order analytical optimality conditions. The proposed approach is based on the previously developed alternance method for constructing parameterized algorithms of programmed control, which heavily relies on the fundamental regularities of the subject area. It is demonstrated that the equations of the optimal regulators within the special intervals are reduced to the linear feedback algorithms based on the measured states of the objects. These algorithms are supplemented with switches at the boundary points to apply the admissible control inputs corresponding to the calculated values of the controlled variable.

分布参数系统中受控变量二次整数估计值的最小化
摘要 在目标集均匀估计的条件下,提出了一种解决具有分布参数的抛物线型系统最优控制线性二次问题的构造方法。最优性准则的形式是在其定义的时空域中对受控状态函数进行积分二次估计。在最优过程的特殊区间内,控制输入的参数化表示具有所需的精度,在这些区间内,控制输入无法使用一阶分析最优性条件来确定。所提出的方法基于之前开发的交替法,用于构建程序控制的参数化算法,该方法在很大程度上依赖于该主题领域的基本规律性。实验证明,特殊区间内的最优调节器方程可以简化为基于物体测量状态的线性反馈算法。这些算法在边界点辅以开关,以应用与受控变量的计算值相对应的可接受控制输入。
