;Currently patients receive rehabilitation which therapists use different therapies with his bare hands to lead patients to do the actions, however, with the limited therapies in a hospital, the number of the patients who can receive the treatment is limited too. And there is a single mode of the existing rehabilitation for hand and foot rehabilitation and the use of a synchronous drive limbs rehabilitation of patients according to their needs of resistance, including electric drive and self-drive mechanism in two ways. The above mentioned common rehabilitation machine does not have both electric drive and drive of their own institutions in the same time. Refer to this papers, which does studies of sports equipment for the hands and feet to make it relevant agencies and with the amplification circuit having a function of rehabilitation aids, its main purpose is to enable patients to achieve self feet and hands of rehabilitation. This system can be divided into four parts: a permanent magnet synchronous motor generator switching control, the permanent magnet and electromagnetic resistance control, and a permanent magnet synchronous motor torque control. When the system is switched to motor mode, the field-oriented control of PMSM with a fixed speed rotation mechanism stimulates rehabilitation. In generator mode, the patient may rotate the mechanism to propel generator operation using a three-phase rectifier diode for DC voltage to generate a stable output voltage which is stored in the buck-boost converter to recharge battery. If higher strength rehabilitation is desired, the permanent magnet and electromagnetic fields can be adjusted by rotating the flywheel to cut the magnetic flux and to generate resisting forces due to eddy current effect to speed up recovery. This rehabilitation system includes the microprocessor (DSP, TMS320F28335/ TMS320F28035) for the control of core operations and PMSM control module (TMDSHVMTRPFCKIT) developed by Texas Instruments to achieve system stability and reliability.
