The mathematic model of thermal drive parts was deduced from the thermal conduction differential equation, and the model parameters were determined based on the experiments and step-by-step fitting method, then the combined control strategy of time optimum control and temperature double-ring control was adopted.
由导热微分方程推导热驱动部件的数学模型,在实验的基础上采用分段逐级拟合指数型函数的方法确定此模型的参数,然后采用时间最优控制和双环温度控制相结合的策略。
