摘要
针对水监测系统中流量控制具有非线性、时变性及不确定性,设计了一种基于PLC的模糊自整定PID控制器。根据偏差和偏差变化率实时调整参数,明显改善了系统的动态和稳态性能,同时采用先进的无线宽带通信系统,满足了系统数据传输实时、高速与高可靠性要求,以及水量测量与闸位开度信息收集与传输的需要。
Aiming at nonlinearity, time-variation and indetermination of flux control for water measurement system, the good controlling effect cannot be gotten if normal PID method is employed. Fuzzy PID parameters adaptive controller based on PLC was designed. According to deviation and deviation variety rates, parameters are adjusted in real-time, so dynamic and steady performance of system are improved markedly. In addition, the advanced wireless wideband communication technique is adopted, meeting the demand of r...
