摘　　要： 在分析变频调速恒压供水特点的基础上提出了控制系统的控制策略,将传统PID控制与专家控制相结合的控制策略,对供水系统建立专家知识库控制规则,根据专家知识库的控制规则来决定投入或切除定速泵台数,用PID控制算法来变频调速,以实现压力的微调,满足更高的供水要求,使水压保持恒定。研究了专家控制在供水系统中的实现方法。 By analysing frequency control constant pressure water supply, control strategy of the control system is proposed, combining the traditional PID control with expert control of the control strategy, the expert knowledge base rules of water supply system are built, based on control rules of expert knowledge base to determine the input or removal of the number of fixed - speed pump with a PID control algorithm in order to achieve the fine - tuning, to meet the higher water requirement, to maintain a constant pressure. Realization of expert control system in the water supply system is studied.

关 键 词： 恒压供水 变频调速 专家控制 控制
