This version of the controller is our new direction in the development of the stabilizing solutions. It will replace the previous 8-bit version of the SimpleBGC controller, keeping 100% back-compatibility, but adding the new fuctionality.
In fact, gimbal based on BLDC motors is very similar to regular gimbal based on hobby servo. The main difference - each axis of rotation passes through the center of gravity (CG) of the "Camera + frame" system and rigidly connected to the BLDC motor. The absence of gear - a fundamental point that lets you use the inertia of the system is not to harm, but for good. In case of ideal balance of the camera, the rotor rotates freely without resistance and even without need of applying extra control force, which allows the camera to unleash from the disturbance from UAV frame. In addition, there is no backlash inherent gears or belts.
To control the motors, a special controller was designed. It receives information from gyroscopes and accelerometers mounted on the camera platform. A standard IMU algorithm is used to define camera inclination angles. With the remote control, operator sets desired tilt angle. PID-controller calculates the amount of compensation and send command to the power unit, which controls the current in the windings and thus the direction of the vector of magnetic field in the stator. Magnetic field moves the rotor to the right position.
Due to using IMU, mechanical part of the system is a very simple. There is no need in complex and expensive high-definition encoders for each axis. Just mount tiny IMU board on the camera platform, connect wires to controller and motors and all done!
It gives impressive quality of stabilization compared with regular servos.
