The most important step for lower extremity exoskeleton is to infer human motion intent (HMI), which contributes to achieve human exoskeleton collaboration. Since the user is in the control loop, the relationship between human robot interaction (HRI) information and HMI is nonlinear and complicated, which is difficult to be modeled by using mathematical approaches. The nonlinear approximation can...
This paper proposes a Constant-current soft starting based on fuzzy control strategy. In this method, the fuzzy control rules are adjusted based on the changes of the starting current in time, which effectively eliminates current and torque oscillation compared with the traditional PID control soft starting. Checking full-voltage method is proposed based on simulation results of the relationship between...
A yaw motion stabilization controller in Electric Power Steering (EPS) system is designed in this paper. According to the linearized four-wheel model of vehicle, a state observer of cornering state variables, such as yaw rate angle and slip angle. In order to improve the drive comfort and drive safety for EPS, a Yaw Rate Generator is designed and a yaw rate stabilization controller is constructed...
In electricity net, three-phase induction motor is the main load, actually, the running motors are mostly working under light-load or zero-load condition. The paper analyzes the changes of the loss and stator current of the motor during voltage-reduce and theoretically proves that stator current of motor is basically of the minimum value when the loss of motor is least, therefore, it is possible to...
