摘要
目的研究一种水源热泵空调系统的智能控制方法,改善系统的控制效果.方法采用参数模糊自整定的控制策略,先对模糊控制器进行设计,再确定参数的原则,再将模糊控制和PID控制相结合,实现PID参数在线自动调整.结果参数自整定PID控制比普通PID控制超调量小5%-10%,调节时间缩短近50%.结论参数自整定模糊PID具有良好的动、静态性能,有效地提高了系统的控制效果,满足了系统的节能技术要求.
An intelligent control method for Water heat pump air condition System( WHPACS ) is studied in order to improve the control performance of the system. Control program of parameters fuzzy auto-adjusting is used. Fuzzy controller is designed and parameters set theory is decided. And then, combining fuzzy control with PID control, auto-adjusting on-line for PID parameters is realized. The over adjusting value for parameter auto-adjusting PID is smaller than normal PID control by 5%-10%, and the adjusting time will be shorten by 50%. The parameter auto-adjusting fuzzy PID control has good dynamic and still performances. The control performances are improved for the system and the energy-saving technology requirement is satisfied.
