A MICROCONTROLLER DISTRIBUTED ARCHITECTURE FOR THE ACTUATOR DRIVE ELECTRONICS ON-BOARD THE EXOMARS ROVER

摘要

The Actuator Drive Electronics (ADE) is one of the pieces of equipment on‐board the Exomars Rover which will cruise to Mars on the second Exomars mission, intended for flight by 2020. ADE gets in charge of driving most of motional actuators of the Rover. This paper describes the microcontroller distributed architecture of the ADE, which is allowing this electronic unit to cope with a number of strong constraints imposed by the program. Assembly, integration and test activities of the ADE become also quite a challenging task due to the complexity of the system the ADE is in charge of. Requirements of motor control in terms of both transient and frequency response have been defined by the Rover manufacturer, under environmental conditions hard to be physically, realistically reproduced at lab.
