A digital controller of stepper motor for Antenna positioning using State Machine in full drive mode

In Satellite, the deployment of antenna at required position is achieved by means of Antenna Drive Electronics (ADE) package. The operational requirement of motors in deployment mechanisms such as slow speed torque, one shot operation can be achieved by the use of stepper motor. In this paper, a digital controller of stepper motor with full drive mode using State Machine is designed. This method is proposed by taking a digital controller of stepper motor with the half drive mode of conventional logic sequence generation as a base. This will result in improved performance by increased torque and reduced clock cycle with the effective utilization of hardware.
