自适应温度控制系统

An Adaptive Temperature Control System

介绍一种模型参考自适应控制算法，所设计的ＭＲＡＣ算法简单，易于在工程上实现。该算法是基于Ｐｏｐｏｖ超稳定性理论进行设计的，温度控制未统由单片微处理器构成，主回路采用ＰＷＭ控制方案。实际应用结呆表明：在升温、恒温、降温阶段的控温精度和性能指标都得到很大提高。该温度控制系统适用于被控对象本数大幅度变化和环境干扰异常严重的情况。

Introduced is a NRAC approach.A design MRAC approach is simple and it realizes easily in engineering.The approach is designed on the basis of Popov’s super-stability theory.The control system consists of the single-chip microprocessor.The PWM control method is adopted in the mair circuit.It is shown that characteristics and precision for temperature,rise constant tempera-ture,dropping temperature are considerably improved.The control system is ap-plicable to the cases of drastical variation in parameters and serious disturbance.
