Abstract

An approach to adaptive control system design which does not involve a direct measurement or identification of the variable process parameters is investigated. Convergence-time relationships and sufficient conditions for system stability are developed when the process is characterized by a variable gain or variable time-constant, and fixed dynamics of any order. The adaptive capability is achieved by employing a model as a reference element and by means of appropriate adaptive circuitry. The adaptive circuitry is simple, easily instrumented, and does not require successive differentiations; the primary function of the adaptive circuitry is one of integration.
模型参考自适应控制系统的稳定性和收敛性
研究了一种不涉及直接测量或识别可变过程参数的自适应控制系统设计方法。当过程具有可变增益或可变时间常数和任意阶的固定动力学时,建立了收敛时间关系和系统稳定性的充分条件。采用模型作为参考元件,通过适当的自适应电路实现自适应能力。自适应电路简单,易于测量,并且不需要连续微分;自适应电路的主要功能是集成。
