A Robust Predictive Control Design for Nonlinear Active Suspension Systems

Abstract

This paper proposes a novel method for designing robust nonlinear multivariable predictive control for nonlinear active suspension systems via the Takagi‐Sugeno fuzzy approach. The controller design is converted to a convex optimization problem with linear matrix inequality constraints. The stability of the control system is achieved by the use of terminal constraints, in particular the Constrained Receding‐Horizon Predictive Control algorithm to maintain a robust performance of vehicle systems. A quarter‐car model with active suspension system is considered in this paper and a numerical example is employed to illustrate the effectiveness of the proposed approach. The obtained results are compared with those achieved with model predictive control in terms of robustness and stability.

A distributed predictive control approach for periodic flow-based networks: application to drinking water systems

“…As future work, the analytical reduction in the number of intermediate iterations should be developed since the rate of convergence towards the Nash equilibrium could be slow in some cases, implying higher computational times. Additionally, the extension of the proposed approach for being applied to non-linear systems and the deep study of systems with delays and robust control schemes (see, e.g., Bououden, Chadli, & Karimi (2016);Yao, Karimi, Sun, & Lu (2014)) will be also considered.…”

“…Furthermore, in order to control the force of hydraulic actuators, the hydraulic valve must be driven by an additional low-power electromagnetic actuator [9]. Moreover, a highly complex controller design is required to account for severe nonlinear dynamics of hydraulic actuators [10][11][12]. Although pneumatic actuators are relatively cheap and there is no liquid leakage, the controllable frequency bandwidth is restricted to 2-3 Hz and they suffer from an air consumption problem [13,14].…”
