摘要
微波热疗的关键是控制热疗温度。目前，微波热疗机多数采用基于PID的控温方案，效果甚不理想。本文在以8098单片机为核心的微波热疗系统中采用了近年来发展起来的一种新型计算机控制算法─—广义预测控制（GPC）控制热疗温度，并且对原算法做了必要的简化，同时辅之以在线辨识受控对象模型参数的方法，使之成为一种自适应控制算法。闭环试验证明这种算法鲁棒性强、控制品质好。
The critical problem for microwave hy-PefLhermia system is its temperature control. At present, PID or some approved PID methods are commonly used for such system but not the ideal one. This paper adopts a new control algorithm - Generalized predichve control (GPC), after being necesstrily simplified and on - line identifited the control objects, to a MCS - 8098 Microwave hyperthermia system and obtains a strong robustness and good control quality effect.
