摘　　要：针对传统喷灌系统耗能大、水压波动大且具有复杂动态非线性特征,结合模糊控制、免疫调节、PID三种技术的优点提出了模糊免疫PID控制算法。仿真及应用结果表明,该方法明显优于常规PID控制算法,可增强喷灌系统稳定性,消除管路压力的波动,确保喷灌质量。Conventional sprinkler control system has following disadvantages： large evergy consumtion, large fluctuation in water pressure, complex dynamic non-linear characteristics. A fuzzy immune proportional-integral-derivative （PID） algorithm, combining the advantage of three above-mentioned technologies, is proposed. The results showed that this method is significantly superior to conventional PID algorithm, and it can enhance the stability of sprinkler irrigation system, eliminate pipeline pressure fluctuations and ensure the quality of sprinkler irrigation.
