针对双容水箱液位会受到外界环境干扰和内部摄动的影响，导致水箱液位出现较大波动等问题，提出将模糊控制技术与PID控制相结合的自适应水箱液位控制方法，设计出自适应模糊PID控制器。-Aiming at the problem that the level of the double-tank is affected by the disturbance of the external environment and the internal perturbation, the water level of the tank is greatly fluctuated. An adaptive tank level control method combining the fuzzy control technology with the PID control is proposed. Adaptive fuzzy PID controller.
