摘　　要：为提高发动机试验台控制系统的性能,对发动机试验台的结构模型进行了深入的研究。针对该多变量复杂系统的特点,依据其结构模型为发动机试验台设计了基于自然、n/M、M/n、n/P和M/P5种控制模式的多回路控制器。充分利用了嵌入式PC可通过PC104总线实现各功能模块之间任意搭接的特点,开发了基于PC104总线的发动机试验台电涡流测功机控制器。试验结果表明:该控制器具有良好的控制能力和鲁棒性。An in-depth study on the structural model of engine tester is carried out for improving the performance of control system for engine tester.Taking into consideration the features of this multivariate complex system and according to its structural model,a multi-loop controller for engine tester based on natural,n/M,M/n,n/p and M/P five control modes is designed.By making full use of the feature of embedded PC,that is,being able to link any function module by PC104 bus,the eddy dynamometer controller of engine tester based on PC104 bus is developed.The test results show that the controller has good control capability and robustness.
