A newly developed simultaneous design procedure for structure and controller is applied to the design of vehicle suspension structure and chassis controller. The design problem is formulated as a stochastic optimization problem for the structural and control parameters. Probabilities that the vehicle system will have unacceptable behavior are used to construct a stochastic performance index, and the design parameters are optimized so that the index takes minimum. The performance of the optimized vehicle system such as stability, command following, robustness, and other characteristics are examined. The results indicate the effectiveness of the simultaneous design.
