“…In [32], a direct-drive electromechanical actuation system has been developed for AMT and DCT systems, and a PID controller achieves the position control of the actuator. In [33], different control algorithms are designed to achieve the position control of an electromechanical shift actuator. Then, the results are compared concerning the shift time and real-time applicability.…”

This paper deals with gearshift control using a face dog clutch as a shifting element. Based on our previous work on dog clutch kinematics, the paper identifies optimal control parameters, such as the optimal angular position difference at which the gearshift process can start, and the linear reference position trajectory. The robustness of the control parameters is shown. Further on, a gearshift mechanism dynamic model is developed, describing elements of an existing gearbox with shifting elements guided by a rotating disc. The coupled linear and torsional dynamics of the actuated shifting mechanism are analyzed. Finally, a linear quadratic regulator is designed and tested in a model in the loop environment for the requested reference trajectory to show the feasibility of the presented method. Two gearshift cases are considered, and the results show that the developed controller can perform a successful gearshift without experiencing a face impact between the gear and the sliding sleeve teeth.
