There is currently an increasing focus on enhancing driver’s seat suspension systems to reduce the vibration transmitted to the human body from road conditions that can negatively affect driver performance, as well as potentially leading to health risks. An active seat suspension system with a closed-loop controller to generate an external force to reduce the vertical vibration transmitted to the seat pan is thus in development, and this paper represents an approach to designing an active seat suspension control system using the linear quadratic regulator control technique. A MATLAB environment was used to simulate the design, while analysis of the driver’s seat was done on a test rig model with two degrees of freedom. The active seat suspension system performance, assessed through adapting the linear quadratic regulator approach, was considered to compare well with passive responses. By generating the optimal values for input control and state matrix in terms of affecting the control action, the simulation results show that the optimal active seat controller has good potential to reduce vertical acceleration by an approximate range of 90%, thus achieving the required ride comfort within the designated cost constraints.
