摘要
在实验的基础上确定了温箱系统温度的数学模型 ,用 PID控制方法对温箱温度控制 ,由于PID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 MATLAB对设计的 PID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 PID控制更理想 .
The mathematic model of a warm case system has been founded on the basis of experiment in this text. And the warm case temperature is controlled by the method of PID. Because PID can't get the request of relatively small exceeding and short regulation time,predictive control is choosed and gets the relatively satisfied result. The design of PID and predictive control are compared with by the MATLAB emulation. The result indicates that predictive control is better than PID obviously in this system.
