摘　　要：以PCT过程控制实验装置为基础,通过对双容水箱液位控制系统的分析建模来决定控制方案;采用增量型PID算法来实现对水箱液位的闭环控制;用凑试法对PID进行参数整定;应用组态王软件运行的液位监控系统来实现液位数据的实时采集、实时显示、历史波形的回放、报警记录以及液位PID控制。实验结果表明,系统能实现液位的无静态误差控制,且具有良好的稳态性能与动态性能。This design is based on PCT process control experimental device,using the double tank water level control system analysis and modeling to decise the control program. Adopting incremental PID algorithm to achieve closed- loop control of water tank level. Employing trial method to set PID parameter. Using of kingview software runs liguid level monitoring system to achieve the liguid level data real-time acquisition,real- time display,history waveform playback,alarm record and the level of PID control. The experimental results show that the system can control the liquid level without static error,and has good dynamic performance and steady state performance.
