This paper discusses the design of an Hinfinity feedback controller which can be used together with an industrial available feed-forward controller. The application is situated in the automotive industry where the goal is drive multi axial hydraulic test rigs, such that some signals measured during a test drive are reproduced on the test rig. The Hinfinity controller is designed with the mixed sensitivity approach in which weighting functions on the sensitivity function S and the complementary sensitivity function T are defined. The weighting functions are specified such that the feedback controller is effective in the frequency band of interest, i.e. between 2 and 25 Hz. The combination of the feed-forward controller and the here designed Hinfinity feedback controller is validated on the front-left corner of a 4 poster test rig (1 input, 1 output). The experimental results show that the proposed control scheme (feed-forward + Hinfinity feedback) improves the response when compared to the classically used feed-forward controller only. Further research will focus on further increasing the performance of the feedback controller and the extension towards the MIMO (Multiple Input Multiple Output) case.
