Abstract
A control system for controlling the rotation of a rotary mechanism such as a propeller housing in a Z-type propulsion apparatus is provided. A command signal and a feedback signal both relating to the rotation of the rotary mechanism are compared with each other. And a control signal which varies at a predetermined inclination is generated when the command and feedback signals differ in amplitude from each other. And a drive unit rotates the rotary mechanism in accordance with the control signal.
