The aim of this study is to control the synchronizer operation in an automated manual transmission (AMT) in which the clutch is eliminated from the driveline to reduce the power losses. The goal of controlling the synchronization phase is to increase the lifetime of the synchronizer by establishing control over the frictional behaviour of such tribological system. The robust control approach starts...
This paper considers the constrained control problem of the friction regimes in sliding lubricated surfaces with the purpose of speed synchronization, wear reduction and increasing the lifetime of the friction lining material. The case study here is the engagement process of the synchronizer cone clutch system. Such synchronizer performs the clutchless gear shifting in a 2-speed automated manual transmission...
In this paper, the robust force control of a solenoid actuator is studied. Such control problem is of interest in the study of gear shifting control in electric vehicles (EVs) equipped with an automated manual transmission (AMT). Experimental system identification together with the finite element method (FEM) is the approach considered in this paper to model the dynamic behavior of the solenoid actuator...
Navigation of spherical robots with constant speed along a straight or curved path is investigated in this paper. A spherical robot driven by motors with constant speed will not necessarily move with constant linear speed. To overcome this problem, one must find a specific velocity function as the motors input which yields a constant linear speed for the robot. The nonlinearity which hides in the...
