Control of brushless DC motors for gimbal stabilizers


S. Tschabold

Semester Thesis, FS16

This semester thesis is about the design of a platform for robust control of a three-axes camera gimbal system with brushless DC motors. As a first step, a custom printed circuit board (PCB) is designed to drive the brushless DC motors with power. Then, different motor control techniques are investigated to control brushless DC motors at low speed. These methods are used to come up with a positioning controller for a single-axis system, where the position estimation is done by an internal measurement unit (IMU). To estimate the performance of the single-axis system, a comparison with one of the best available gimbal controller is performed. Finally, the position controller is extended to stabilize a three-axes gimbal system.
