The combined feedforward and feedback control structure, well solved the problems of low control precision, weak timeliness and high feedback overshoot, and has been widely applied in vehicle dynamic control [87]. Nagai et al. applied the combined feedforward and feedback control structure in control over direct yaw moment [30, 42, 43, 88–93], with the control structure as shown in Fig. 1. According to this solution, the target of feedforward is the desired direct yaw moment when steady-state response is satisfied, and the feedforward direct yaw moment Mff generally depends on the steering angle δ of front wheel and feedforward control gain G ff , as shown in Eq.

However, through his subsequent study, it was discovered that the target side slip angle can be designed as 0 since it is generally very small. Therefore, the control side slip angle was set as 0 [30, 43, 90–93] in his subsequent study as well as others’ study [6, 28, 94, 95].
