Research Topics:Design of Current Sensors Using a FBG,
Design of automatic torque adjustment for electric
motorcycles, Design of Intelligent Air-Conditioning System
Using DSP,

Design of Current Sensors Using a FBG:

The fiber
current sensor is used by the magnetic field induced by the
different current magnitude, and center wavelength of fiber
bragg grating will shift. The different reflection response of
optical current sensor is detected by Optical Spectrum
Analyzer (OSA), the current magnitude will be measured

Design of automatic torque adjustment for electric
motorcycles:

The power of electric motorcycles are supplied
by the single-quadrant chopper circuit and differential amplifier,
the PWM (Pulse-Width-Modulation) method is used, then the
step changed torque adjustment is obtained


Design of Intelligent Air-Conditioning System Using DSP:
The compressor of traditional air-conditioning system is
operated stop and start frequently, this manner not only more
electricity is used but also the machine service time will be
shorter. Since the speed control of air-conditioning
compressor is nonlinear, the fuzzy theory is proposed for the
controller design, the control signal of compressor is
obtained by digital signal processor (DSP)
