Multiple Model DMC and its Application in the Hydraulic Dynamometer System
多模型DMC及其在水力测功器系统中的应用

In light of the features and requirements of the hydraulic dynamometer system in the FZD II(P) type engine test cell,we analyse the drawbacks of PID and nonlinear predictive controls,and put forward a multiple model DMC control scheme with improved cost criteria.The scheme meets the demands of speed,accuracy and multiple objects for the test of BN492QA type engine.
