| 摘 要： | 针对温度控制系统的大滞后特点,采用Smith预估控制算法进行控制,在此基础上提出了一种改进PID控制算法.仿真结果表明改进的PID控制算法具有较强的稳定性和鲁棒性,既能有效地抑制大滞后、时变的影响,又对模型参数的变化具有很强的适应性,能取得良好的控制性能,是一种实用而简便的大滞后炉温控制方法.

| Abstract: | The large time-delay systems widely exist in industry process.As the temperature-controlling system has the characteristics of large time-delay,Smith’s predictive control algorithm is used at first and then on this basis,an improved PID control algorithm is proposed.The simulation results show that as compared with Smith’s the improved PID control algorithm has the following advantages:it is stable and robust,it inhibits the large time-delay and time-varying effects,it has strong adaptabilities for various changes in the parameters.Its good performance illustrates,it is an appropriate and simple control method for the system having a large time-delay. |
