摘要：In the research project, the goal is to reduce PSD on acceleration of sprung mass by automatic control of active dampers in vehicle. For two-DOF vehicle suspension model, control strategies are being developed and tested in simulation models. The acceleration of the sprung mass, dynamic tyre load between wheels and road and dynamic deflection between the sprung mass and the unsprung mass are determined as the evaluation targets of suspension performance. The control algorithm, which is called LMS adaptive control, makes it possible to reduce RMS on acceleration of sprung mass significantly. For LMS adaptive control suspension, compared with passive suspension, acceleration PSD of sprung mass acceleration under the road input model has all decreased largely as 8-10 times in high frequency resonance band or low frequency resonance band.
