Based on current research into the mathematical model of the permanent magnet synchronous motor (PMSM) and the feedback linearization theory, a control strategy established upon feedback linearization is proposed. The Lie differential operation is performed on the output variable to obtain the state feedback of the nonlinear system, and the dynamic characteristics of the original system are transformed into linear dynamic characteristics. A current controller based on the input–output feedback linearization algorithm is designed to realize the input–output linearization control of the PMSM. The current controller decouples the d–q axis current from the flux linkage information of the motor and outputs a control voltage. When the motor speed reaches above the base speed, the field-forward and straight-axis current components are newly distributed to achieve field weakening control, which can realize the smooth transition between the constant torque region and weak magnetic region. Simulation and experimental results show the feasibility and viability of the strategy.

“…To extend the power and speed operation range which is constrained by a given DC-link voltage, the FW control is usually adopted to weaken the air-gap flux by utilization of [14][15][16]. Based on the conventional decoupling vector control with dq-axis current regulation for a single three-phase machine, the strategies of FW control can be classified into feed-forward [17][18][19][20][21][22] and feedback methods [16,[23][24][25][26][27][28][29][30][31][32]. The FW control of the feedforward method has the advantage of excellent dynamic performance; however, the accuracy of FW current from the feed-forward method relies heavily on the accuracy of machine parameters, such as the flux-linkage and inductances, which might vary with loads and temperature [18,33,34].…”

“…From another perspective, the longitudinal and lateral slips of wheels and the variations of parameters can be treated as some unknown disturbances and uncertainties in the vehicle system. Several methods have already been used for the stability control of land (ground) vehicles, and the proportionalintegral-differential (PID) is one of the classic control approaches [11]- [12]. However, the PID control is hard to achieve high control performances for complicated systems under unknown conditions.…”

Off-road vehicles always experience serious uncertain longitudinal and lateral slips when running on soft and slope terrains, and some parameters of the vehicles, such as the cornering stiffness and the slip of wheels, are always not constants. In this paper, control strategies for the torque of each wheel and the rear-wheel-steering angle are proposed to maintain a stable velocity and approach an ideal reference model for the off-road vehicle by using second-order sliding mode (SOSM) techniques. An observer is constructed to estimate the actual sideslip angle of the vehicle with the consideration of uncertainties and disturbances of the system. Then, with conditions of bounded uncertainties and disturbances, composite super-twisting (ST) controllers combined with a velocity controller are designed to generate the total torque, the differential torque, and the rear-wheel-steering angle. On this basis, the proposed controllers have been verified to lead good robustness for maintaining the stable velocity and approaching the ideal reference model by using an optimal torque allocation controller at a lower layer. In comparison with conventional yaw moment controllers without the rear-wheel-steering control, the proposed controllers are shown to be more effective.
