Ergodic control applied to car suspension design

Stochastic ergodic control is used to compute feedback laws for semiactive vehicle suspensions. The authors present an overview of a study supported by Renault and conducted by J. Alanoly and S. Sankar (1988). For the practical implementation, the Hamilton-Jacobi-Bellman equation can be numerically solved, which gives an approximation of the optimal law. Another possibility is to seek for the best feedback in a given class of parametrized feedbacks via a stochastic gradient algorithm.<
