Abstract
A control system of resisting and assisting force for a rehabilitation apparatus includes a motor, a resistance adjustment control device and a motor output force control device. The motor drives the rotating wheels of the rehabilitation apparatus and controls the rotating wheels to produce resistance and power assisting force. The resistance is designed by imitating the frictional force of different road conditions. The motor output force control device gathers the resistance value preset by the resistance adjustment control device. and the force of a patient pushing or pedaling the rotating wheels and then controls the compensation and the output force of the motor to push the rotating wheels. When the resistance is adjusted to become increasingly larger and larger by the resistance adjustment device, the force of a patient's hands or legs will gradually increase and finally able to push or pedal the rotating wheels by himself.
