发动机瞬态工况试验台是一种多输入、多输出、紧耦合、非线性、大滞后的复杂系统，传统的控制理论很难达到理想的控制效果．为此介绍了预测、去耦、智能模糊控制理论应用于发动机瞬态工况试验台的研究．试验证明，此理论对复杂系统具有很好的适应性． The engine transient condition test bed is a complex system with multiple inputs, multiple outputs, tight coupling, nonlinearity and large hysteresis. The traditional control theory is difficult to achieve the desired control effect. To this end, the theory of predictive, decoupling and intelligent fuzzy control is introduced to the research of engine transient condition test bed. Experiments show that this theory has good adaptability to complex systems.
