ABSTRACT:
An electro-rheological (ER) fluid damper control system employs fuzzy logic to attain real time control in a highly responsive manner. The ER fluid damper is interposed in a vehicle between its sprung mass (vehicle body) and unsprung mass (suspension). Signals corresponding to the velocity of the sprung mass and the relative velocity between the sprung and unsprung masses are generated by pairs of accelerometers and electronic integrators. A fuzzy rule, taking into account weighted values of these input signals, is applied to the signals to determine an output value which, in turn, establishes a control signal for application to the electrodes of the ER fluid damper. As the velocity signals change, the voltage applied to the electrodes also changes, thus adjusting the fluid viscosity and mechanical responsiveness of the ER fluid damper.
