摘要
针对飞机上电气设备的散热问题,设计了一种基于PAC,采用专家PID控制策略进行控制的系统.该系统由可编程自动控制器(PAC)构成主要的控制核心,完成系统的监测和报警,并且能够自动调节系统的工作温度;采用专家PID作为系统的控制策略,能够很好地解决温度调节所遇到的非线性、强耦合、时变和时滞等特点,使其在最快的时间内达到系统的控制目标.实验应用表明,系统可靠性高,控制性能好,具有很好的应用价值.
In view of the electrical equipment heat on the plane, a kind of control system based on PAC which using the expert PID control strategy has been designed. The system which the programmable automatic controller （PAC） system has been used as a major control core complete the monitoring and automatic adjustment the temperature of the system. As the system control strategy, the expert PID can solve the problem of the characteristics which comprise the temperature system ＇s nonlinear, strong coupling, time - varying, the time delay and others very good, and achieve the system＇s control objective in the fastest time. The practical application shows that the system has high reliability, excellent performance of the controller and has the very good application value.
