按照偏差的比例、积分和微分规律进行控制量运算的调节器,称为PID调节器。模拟PID调节器,是连续控制系统中结构简单、参数易于调整、通用性、互换性能强、技术最为成熟的定型仪表,因此在工业生产过程的控制中获得了广泛的应用。模拟PID调节仪表在使用中,或者因为控制规律选择不当,或者因为参数校调的不妥,或在选择性调节系统中工作,或配置于串级系统中而且参数整定的不对头,碰到系统开停、大幅度提降整定值或有强烈扰动时,会产生积分饱和问题。在这种情况下, According to the deviation of the proportion, integral and differential regulation of the amount of control operation of the regulator, known as the PID regulator. Analog PID regulator, continuous control system is simple in structure, easy to adjust the parameters, versatility, interchangeability, the most mature technology stereotypes instrument, so in the industrial process control has been widely used. Analog PID regulator in use, either because of improper selection of control laws, or because of improper adjustment of parameters, or in the selective adjustment of the system work, or configured in the cascade system and parameter tuning of the wrong, hit the system Open stop, significantly lower set point or a strong disturbance, will have the problem of integral saturation. under these circumstances,
