Motivated by the walking capabilities of human limb, this paper presents a design of active suspension based on a developed neuromuscular-like control. The underlying mechanism was inspired by modeling the nonlinear damping property of the biological muscle-reflex system. Simulations performed with a quarter-car model verified the feasibility of controlling an active suspension. To optimize the suspension performance, the least-mean-square (LMS) algorithm was applied to determine the proper values for the control parameters in the developed model. In addition, two design methodologies using the model to control an active suspension system were also proposed. Simulation results on a quarter-car model demonstrated the superior effectiveness of the neuromuscular-like model in controlling an active suspension system.
