【摘要】 在周围环境温度不同的情况下,通过实验的方法得出了3个恒温箱的数学模型。针对恒温箱这个时变的系统,建立了一个可以对恒温箱实现高精度控制的控制算法数学模型,并应用在所建立的3个恒温箱模型中。该控制器不仅保持了常规PID控制器的优点,而且具有很强的鲁棒性和适应性。仿真结果表明系统可以达到很好的动静态性能指标。更多还原

【Abstract】 Three math models for a thermostat are built by an experimental method at different ambient temperatures.A math model of the control algorithm for highly accurate control of the thermostat is built on the thermostat serving as the time-varying system and is applied in above three models.The controller not only keeps advantages of conventional PID controllers,but also has strong robustness and adaptability.Simulation experiments show that the system may provide good dynamic and static indexes.更多还原
