Abstract
This paper presents a motor position control algorithm for an automated manual transmission (AMT) of the agricultural tractor, based on modified linear quadratic tracking (LQT). In this paper, the modified LQT is derived from the conventional LQT by applying the Luenberger observer in order to design an output feedback controller. A dynamic model of the actuator is derived to represent characteristics of the worm geared DC motor and the proposed control algorithm is applied and tuned with the model. The proposed position control algorithm of the worm geared motor using the modified LQT can improve disturbance rejection performance without changing the hardware configuration of the AMT. The simulation results show the validity of the proposed control algorithm.
