Robust Control of Vehicle Active Suspension and Its Verification

Original language description

— Suspension systems influence both the comfort and safety of passengers and protect road surface from damage, too. In the paper, energy recuperation and management in automotive suspension systems with linear electric motors that are controlled by a designed robust Hinfinity controller to generate a variable mechanical force for a car damper is presented. The robust controller is necessary to design for the suspension system because the vehicle parameters often vary in a wide range. Especially the body mass varies for every single drive. Vehicle shock absorbers in which forces are generated in response to feedback signals by active elements obviously offer increased design flexibility compared to the conventional suspensions with passive elements (springs and dampers). The main advantage of the proposed solution that uses a linear AC motor is the possibility to generate desired forces acting between the unsprung (wheel) and sprung (one-quarter of the car body mass) masses of the car, providing good insulation of the car sprung mass from the road surface roughness and load disturbances. As shown in the paper, under certain circumstances linear motors as actuators enable to transform mechanical energy of the vertical car vibrations to electrical energy, accumulate it, and use it later when needed. Energy consumption and accumulation control enables to reduce or even eliminate the demands on the external power source. In particular, the paper is focused on experiments with active shock absorber that has been taken on a unique verification device we designed and constructed as well as the way we developed an appropriate input signal for the test device that as a real road disturbances act upon the vibration absorber. Obtained results of various experiments are shown and evaluated at the end.
