Adaptive Fuzzy Controller for Handling Imrovement of Four-wheel-steering Systems
نویسنده
چکیده
A fuzzy control design method for four-wheel-steering vehicles, using fuzzy models, is presented. The design model is obtained from a vehicle model using fuzzy modeling approach. In the first step of the controller design, an optimal steering controller is proposed for each local model using LQR method. Then, the local controllers are combined using fuzzy rules to form a fuzzy controller. In the next step, an adaptive fuzzy controller is obtained using adaptive control law. Simulation results show the good performance of the proposed controller as compared to the nonadaptive fuzzy controllers. Copyright 2002 IFAC

Hybrid state-feedback sliding-mode controller using fuzzy logic for four-wheel-steering vehicles
This paper presents a fuzzy controller for high-speeds four-wheel-steering vehicles based on the state feedback and the sliding-mode control methods. In the proposed fuzzy controller, the consequent part of the fuzzy IF-THEN rules consists of either a sliding-mode controller or a state-feedback controller. Also, it will be proved that, if every fuzzy rule is stable in the sense of Lyapunov for ...

متن کاملDesign of the Active Steering Fuzzy Controller with the Degree of Non-uniformity for a Scaled Railway Vehicle
This paper presents a technique for improving the performance of active steering fuzzy control systems by adequately changing the widths of triangular fuzzy membership functions. Running curve railway, the wheelsets of conventional vehicles generally misalign radically with the track increasing wheel/rail contact forces and resulting in increased wheel and rail wear. To solve these problems, mo...
