Abstract: |
In this paper, modeling and simulation
of nonlinear, Half-car Active Vehicle Suspension System (HAVSS) reinforced
with PID controller is presented. The model has 4 degrees of freedom;
comprising of heave movements of the front and rear
axle, pitch and heave motions of the unsprung mass
of the vehicle. The vehicle is excited by a triangular bump on an otherwise smooth
road. The objective of the presented model is to isolate the vehicle body
from these road disturbances in order to maximize passenger ride comfort and
retain continuous road-wheel contact. PID controller is used to supress the vibrations generated from the road unevenness.
Newton’s approach is used in system modeling due its simplicity over D’Alembert’s and Lagrange’s
approach. The simulation, carried out in MATLAB environment, vividly shows
the superior performance; in both effectiveness and
robustness of the HAVSS over its passive control counterpart. |
