| Title: |
Systems and Methods for Controlling the Position of a Moving Light Fixture |
| Abstract: |
Moving light fixture and method for controlling the position of a moving
light fixture. In one example, the moving light fixture includes a
housing, light sources, a stepper motor, a magnetic position encoder, and
an electronic controller. The stepper motor rotates the housing. The
magnetic position encoder is configured to transmit a position signal
indicating an angular position of the housing. The electronic controller
determines the angular position of the housing based on the position
signal. The electronic controller also determines a full step of the
stepper motor based on the angular position of the housing, and a micro
step of the stepper motor. The electronic controller also determines a
current position of the moving light fixture based on the full step and
the micro step. The electronic controller drives the stepper motor to
move the moving light fixture from the current position to a target
position.
