308 Robust Control of Engine Test Bed

Abstract

In order to evaluate performances of an engine that is developed, there is a way that a certain vehicle model is virtually performed by using a low-inertia dynamo. This paper shows the vehicle model simulated in SIMULINK and the construction that the low-inertia dynamo generates the torque according to the simulation. We use a hydrodamper with strong nonlinear property to connect the engine and the low-inertia dynamo. By applying H_∞ theory and μ-synthesis we design the controller for the plant with a minor loop of the shaft torque. It is verified that the robust controller designed is effective for the engine test bed by simulations and experiments.
