动态加载, 直接转矩控制, 模型参考控制, 专家PID

Dynamic loading is an important technology of vehicle testing device.In order to overcome the difficulty of torque control in traditional loading method,DTC was adopted.Model parameters varied greatly according to different types of vehicle,so model reference control was taken to improve the model's adaptability.Aimed at reducing dynamic errors further,an expert PID control was selected to design the torque controller.A simulation model was set up. Simulation outcome shows that compensating torque can be rapidly regulated according to demands of dynamic loading.Stable-state error is less than one percent,and dynamic error is much more less than that of traditional PID.In the

end,a conclusion is drawn from comparison study that dynamic loading with electrical simulation proposed meets the demands of vehicle testing,and its synthetic performance is superior to traditional static loading.
