Clutch torque estimation is an important problem in automotive transmission control. Particularly, a self-energizing clutch actuator system has a novel mechanism to amplify the clutch torque for reducing actuation energy. Instead of low energy consumption, the clutch torque is highly sensitive to the actuator stroke, which makes the torque detection difficult. The nonlinear disturbance observer is...
This paper proposes a periodic adaptive disturbance observer (PADOB) to control a PMLSM (Permanent Magnet Linear Synchronous Motor). The PADOB consists of a classical linear DOB and an adaptive mechanism which has been known as the periodic adaptive learning control (PALC). The key idea is to compensate parametric errors between the actual plant and the nominal model of DOB and disturbance forces...
Automated Manual Transmission vehicles are generally equipped with the servo-actuated clutch engagement system. In that system, shift quality depends on the engaging time and controlling the clutch normal force. It is therefore crucial to pay attention to the control performance in order to guarantee smooth engagement of the clutch. This article proposes the control architecture that consists of the...
