在实验的基础上确定了温箱系统温度的数学模型, 用P ID 控制方法对温箱温度控制, 由于

P ID 控制不能同时满足较小的超调量和较短的调节时间的要求, 为此必须采用其它先进的控制策

略, 选择预测控制获得较满意的结果. 并用MA TLAB 对设计的P ID 控制和预测控制分别进行了仿真和比较, 结果表明预测控制在本系统中比P ID 控制更理想.-In the experiment based on a warm box system temperature of the mathematical model, using P ID control box temperature control of temperature, because of P ID control at the same time should not meet the smaller overshoot and shorter settling time requirements, for which must use other advanced control strategies, prediction control to choose a more satisfactory results. and MA TLAB design of P ID control and predictive control, respectively, and compare simulation results show that the predictive control in this system than the P ID control better .
