Research was conducted on vehicle stability control algorithm for four wheel drive (4WD) mini electric vehicle (EV) basing on vehicle dynamics model. The whole vehicle model with eight degrees of freedom was constructed using graphics modeling technology and S-function in MATLAB/Simulink, which includes 4 wheel rotation speeds, front wheel steering angle, vehicle lateral speed, longitudinal motion,...
In this paper, a 4 wheel steering vehicle (4WS) was used as a template and a vehicle was modeled (experimental) by using 2 degree of freedom system. The dynamics governing the Yaw behavior of a vehicle has been simulated with MATLAB/SIMULINK software. A controller, working by fuzzy logic was then designed. A relationship between front and rear angle of tires in different speeds and different front...
A novel fuzzy logic controller based on T-S model is proposed for automatic generation control (AGC) system after deregulation. Since the AGC system is now exposed to sudden, larger changes introduced by deregulation policy, the nonlinearity must be concerned. In this paper, the generation rate constraint (GRC) is firstly constructed in T-S model to design the fuzzy logic controller, while the valve...
In the paper the dynamical performance and sensitivity to the motor parameter changes of the sensorless induction motor drive with MRAS type speed and flux estimator is demonstrated. The stability analysis of the stator current-based MRASCC estimator of the induction motor is presented. The influence of equivalent circuit parameter changes of the induction motor as well as coefficients of the adaptation...
