Mitsubishi Electric, Osaka, Japan
Research Engineer (and part time Ph.D Student) 1996 – 1998
I was working full time in Mitsubishi Electric since August 1996 until March 1998. During this time I have contributed significantly to major projects in the Transportation Systems Department, as well as working in the Industrial Electronics and Systems Research Laboratory. Due to the size of transportation projects, this project work has required a large amount of teamwork, excellent communication, and initiative.
I designed the hardware, software, and user interface for projects ranging from industrial transport controllers to game boy camera games.
A major benefit of my time in Japan was that I learnt a great deal about the culture, life-style, and company operations in Japan. This invaluable experience could only be gained by actually living and working in Japan. Furthermore I became more and more proficient in spoken Japanese, and although not fluent yet, I believe I greatly improved during my time there. Furthermore I have written two international papers describing my work in Mitsubishi for international conferences. A brief outline of the work I was involved in is listed below:
Mitsubishi Electric Engineering Work :
1. Design and development of game boy camera game
2. DSP Based Induction Motor Control (both VVVF and Vector Control)
3. High Voltage Inverter / Converter Design for high-speed trains.
4. Unity power factor and electromagnetic noise reduction PWM control
5. Development of fuzzy logic based anti skid control algorithm.
6. DSP based assembler implementation of anti skid control.
7. Simulation of vector control method for traction drives using Matlab/Simulink.
8. Implementation and testing of vector control scheme on TMSC30 based DSP unit.
Mitsubishi Electric Business Work:
1. Presentation to, liaison, and negotiation with customers in Hong Kong (which involved 3 business trips to Hong Kong in the past year). This required superior communication skills.
2. Preparation of tender documents for Thailand and Singapore train authorities.
Important breakthrough achievements included:
1. Developing a fuzzy logic brake controller for use in high-speed trains using real-time embedded controller (interface, hardware and software in C and assembler was developed). It is now being used in trains in Japan and around the world (details were published in the IEEE Transactions on Systems Man and Cybernetics Part C).
2. Embedded hardware/software work.
