摘　　要：为了适应水轮机调速系统工况不断变化的控制要求，提出了一种把常规ＰＩＤ算法和模糊控制算法结合在一起的复合控制算法。这种算法的特点是利用人工经验和知识实时调整ＰＩＤ参数，从而改善控制系统性能，提高调节品质和适应能力。仿真试验表明，采用这种算法的水轮机调速系统具有良好的控制性能和鲁棒性。Abstract In order to comply with the control requirements of incessantly changing operational conditions, an assembled control algorithm is proposed for hydroturbine speed governing systems, which is a combination of conventional PID and Fuzzy control algorithm. This algorithm is featured by real time adjustment of PID parameters with the help of human experience and knowledge, wherewith performance quality and adaptability of control systems are improyed. Simulation tests show that speed governing systems of water turbines, which make use of such an algorithm, exhibit good robustness and controlability.
