A PRELIMINARY STUDY INTO THE APPLICATION OF ACTIVE FORCE CONTROL STRATEGY TO AN AUTOMOTIVE SUSPENSION SYSTEM

KeywordsAbstract
This paper describes a novet approach 10 control an all/olllotire suspension system employing
active force control (Af"C' strategy. AFC has been demonstrated 10be very robust and effective in controlling dynamical system subject to disnubances, uncertainties, parametric changes and
operating conditions. In the slUdy, AFC is explicitly implemented fa provide a robust mechanism
for the control of the suspension s)'s/em that is subjected to a number of operating and loading
conditions pertaining to road input disturbance and delibermel)' introduced external
disturbances. The classical proportional and derivative (PD) cuntroller is also incorporated into
the comrol scheme that could f urther enhance Ihe eJfecrivlmess of the proposed method, An
iterative learning technique was embedded into the control loop to obtain the estimated mass
required by the AFC strategy to effect the control action. A modelling and simulation study ""as
carried out on a quarter car model system with the applied control scheme taken into account. A comparative study heMeen the AFC and pure PD schemes wus performed to demonstrate the
differences in the performance,
