Abstract

Although most of the control designs are based on position and velocity feedback, in general acceleration is easier to measure than position
or velocity. In contrast to position and velocity sensors, accelerometers are low-cost and efficient measurement devices. As a natural result of
these, they are widely used in mechanical systems. Thus, these situations increase the importance of acceleration feedback control designs for
mechanical systems. Passing the acceleration filter through a second order filter with substantial damping and generate a force feedback proportional to the output of the filter is one of the popular approaches for the acceleration feedback control design. Since this control approach is
based on adjusting two control parameters properly, it is easy to use and generally gives satisfactory results. In this study, an automative active
suspension system design for a quarter bus is addressed by utilizing the mentioned acceleration feedback approach. Modeling approach of an
active suspension system of a quarter bus, acceleration feedback control design and effect of the change of control parameters are examined in
a detailed manner. Performance of the designed controller is demonstrated via numerical simulation results realized in Matlab.
