结合制冷系统中吸气温度对性能测试的重要影响，以及ＰＩＤ控制算法的优缺点，提出采用Ｐ—ＦｕｚｚｙＰＩＤ双模控制方法，同时ＰＩＤ采用不完全微分型，并给出了ＦｕｚｙＰＩＤ的基本设计过程。 Combined with the important influence of suction temperature on the performance test in refrigeration system and the advantages and disadvantages of PID control algorithm, P-FuzzyPID dual-mode control method is proposed. At the same time, PID is not completely differential type, and FuzyPID basic design process is given.
