The brushless DC motors (BLDC) have been widely applied to the motion control over a wide range of industrial applications because of its superior characteristics of high efficiency, high power density, easy control and maintenance, in recent years. However high performance motor drives require fast and quick speed response caused from system disturbance and parameter variations. In order to obtain...
The aim of this paper is to present the design and implementation of an electric foot rehabilitation machine that uses an advanced RISC (reduced instruction set computer) machine (ARM) microcontroller based brushless dc (BLDC) motor drive. The function of the electric foot rehabilitation machine is to help patients who need physical therapy for a foot. The goal is for patients to have increased muscle...
To improve the drawback of inconvenient and bulk weight of exercise machine, an arm strength training machine based on PMSM drive controller which has the advantages of user friendly, light weight, movable, and convenient, is designed and implemented in this paper. The hardware design based on a microcontroller is analyzed and discussed. The software programming is developed in MPLAB integrated development...
The establishment of interactive communication between arm strength training machine (ASTM) and the people will make the exercise and rehabilitation therapies become more friendly. This paper presents a friendly human interface for ASTM, in such a way to reduce the occurrence for improper operation of exercise machine. The system hardware consists of a universal asynchronous receiver/transmitter (UART)...
Most of the conventional exercise apparatus use the iron or aluminum for weight lifting. Without assistance of professional trainer or qualified rehabilitation therapist, physical injury could be occurred when exercises or rehabilitation therapy improperly proceed. This paper presents a friendly windowing interface for an arm strength training machine based on the ARM controller, in such a way to...
In order to cultivate talents and raise the design ability for power converters at engineering education on campus, the design methodology of a flyback dc/dc converter is introduced step by step in this paper. First of all, the fundamental of switching power converters is analyzed and described in this paper. Later, the power converter is modeled and simulated. The open and closed loop controls of...
