Anti-backlash gear control device
Abstract:
An anti-backlash gear control device is disclosed that includes a first bias module operable to generate a first bias to be applied to a first motor operable with a first gear, and a second bias module operable to generate a second bias, opposite the first bias, to be applied to a second motor operable with a second gear. The first gear and the second gear are operably connected to a load gear, such that rotation of at least one of the first gear and the second gear causes the load gear to move. Additionally, a command module can receive a drive command and output at least one of first and second command signals based on the drive command to be summed with the first and second biases, respectively, to generate first and second drive signals to operate the first and second motors to drive the first and second gears, respectively.
