The main body of this investigation focuses on the development of an analytical and numerical design procedure that yields mechanism to control effectively vibrations of a ground vehicle suspension using Linear Quadratic Gaussian (LQG) approach. The theoretical aspects of an optimal active and suboptimal Semi-active three-dimensional ride control for a typical passenger car is presented. The design is based on a seven-degree-of-freedom mathematical model. The performance index employed is a weighted sum of mean squared values for the passenger seat acceleration, secondary and primary suspension deflections and sprung mass forces. Computer simulation results show that the ratios of the normalized performance indices for Passive, Semi-active, and Active suspension stay within the vicinity of 4.5 to 1.5 to 1 respectively.
