Abstract

The application provides a driving system applied to a motion platform. The driving system adopts a brushless direct current (DC) motor; the counter electromotive force produced by the brushless DC motor is a square wave or a sinusoidal wave; the counter electromotive force is basically unchanged within a phase shifting period; the output drive torque fluctuation is smaller. Therefore, accurate measurement does not needed to be continuously carried out on the angular position of a rotor of the motor like the prior art, so that a high-accuracy position sensor is not needed, and a low-accuracy Hall sensor only needs to be used; therefore, the cost of the driving system can be lowered.

Description

technical field [0001] The invention relates to the field of electromechanical control, and more specifically, relates to a driving system applied to a dynamic platform. Background technique [0002] Dynamic platforms, such as dynamic seats, spinning bicycles, etc., can provide users with dynamic experiences such as rising, falling, left and right, front and rear tilt, rotation, etc. synchronously with the visual content, and improve the user's sense of reality. [0003] The drive system of the existing dynamic platform uses a permanent magnet AC servo system, which includes a permanent magnet AC servo motor, a position sensor and a driver. Since the counter electromotive force generated by the permanent magnet AC servo motor is a sine wave, when it is necessary to ensure permanent When the output driving torque of the magnetic AC servo motor is constant, it is necessary to continuously measure the angular position of the rotor of the permanent magnet AC servo motor, so a hi...
