“…A time invariant discontinuous feedback law is applied for regulation control and a sliding mode control is proposed for turning control. A dynamic model of a WMR under slip conditions has been developed and controlled with the sliding mode controller in Ghobadi and Dehkordi (2019). In this model, longitudinal and lateral traction forces are estimated linearly as a function of longitudinal and lateral slip.…”

“…But, under real conditions, the wheel slip is inevitable because the WMR always slips on a slippery surface (wet or icy roads and rough terrain) and at high speed (Tian and Sarkar, 2014). Thus, modeling mobile robots without slip leads to results with insufficient accuracy (Ghobadi and Dehkordi, 2019). So, it is necessary to use controllers to drive the WMR to a desired trajectory and to ensure efficient performance considering the wheels’ slipping.…”

“…In [15], the authors proposed a brake control system to prevent lateral skidding of commercial aircraft wheels using the backstepping method. In [16], Sidek and his colleagues developed an input-output linearized controller to represent the relationship between the torque at the actuator and the traction function of wheel slippage. Researching in [17,18], the authors treated wheel slippage as a bounded disturbance affecting the control system state.…”

“…Moreover, the difference in slip may occur due to vehicle being turned or because of different road conditions for different wheels [3]. When a vehicle is traveling at high speeds and turns, its outer and inner wheels rotate at various speeds, which must be controlled by a controller to achieve a desired turning radius without losing its stability.…”
