This paper first presents a simplified single wheel model for underground mining electric vehicles with bounds of system uncertainties. Then, a fuzzy parameter tuning (FPT) technique is used to adjust the parameters in the sliding mode control (SMC) to improve system stability and robustness at an unexpected external disturbances and unbound system uncertainties. The comparison of the simulation results...
This paper presents the design and the simulation test of a Takagi-Sugeno (TS) fuzzy lane keeping output feedback controller. The vehicle control law has been developed based on invariant sets and quadratic boundedness theory, based on a common quadratic function. The TS fuzzy model is able to handle elegantly the nonlinear behavior the vehicle lateral dynamics. The computation of the control law...
In this paper we present one of the concepts of vehicle seat vibration damping, using a fuzzy controller. We used a fuzzy controller as a part of a semi-active vehicle suspension system, which consists of semi-active air spring and semi-active damper. System is implemented between the cabin floor and vehicle seat. Fuzzy controller is designed to adjust the stiffness of the air spring and damping of...
