Abstract
A control system of a motor-driven moveable platform is provided to control speed of a moveable platform. The control system of the motor-driven moveable platform includes a subtractor, a controller, and a signal converter. The subtractor produces an error speed, the controller produces a speed control signal, and the signal converter produces a speed drive signal including an accelerated drive signal and a decelerated drive signal. The accelerated drive signal and the decelerated drive signal are provided to control acceleration and deceleration of the moveable platform.
Claims20
A control system of a motor-driven moveable platform configured to control speed of a moveable platform, the control system of a motor-driven moveable platform comprising:
- a subtractor configured to receive a reference speed and an actual speed, and calculate a speed difference value between the reference speed and the actual speed to acquire an error speed,
- a controller configured to receive the error speed, the actual speed, and an absolute value of a target speed to calculate a speed control signal, and
- a signal converter configured to receive the speed control signal, the actual speed, and the absolute value of the target speed to calculate a speed drive signal, wherein the speed drive signal comprises an accelerated drive signal and a decelerated drive signal,
- wherein the accelerated drive signal and the decelerated drive signal are provided to control acceleration and deceleration of the moveable platform.
A method of controlling a motor-driven moveable platform, the method comprising the steps of:
- (a) providing a reference speed, an actual speed, and an absolute value of a target speed,
- (b) providing a controller, and calculating a speed control signal by the controller according to the reference speed, the actual speed, and the absolute value of the target speed,
- (c) providing a signal converter, and calculating a speed drive signal by the signal converter according to the speed control signal, the actual speed, and the absolute value of the target speed, wherein the speed drive signal comprises an accelerated drive signal and a decelerated drive signal, and
- (d) controlling acceleration and deceleration of the moveable platform according to the accelerated drive signal and the decelerated drive signal.
