1. Postdoctoral Research Fellow.         Fractional Order Control in Hard Disc Drive Servo System Project.
    CSOIS/ECE/USU                              Oct. 2009 –

The fractional order control theory is applied in the Hard Disc Drive Servo System. The performance
improvement with fractional order controller is significant. The systematic tuning and design method
for the fractional order proportional derivative controller is proposed and implemented. Meanwhile,
the fractional order filter is used for the vibration compensation in the Hard Disc Drive Servo System,
and the performance under vibration is improved obviously.

(I) Running the Fractional Order Mechatronics Control Group and acting as the group leader in CSOIS, Dept. of ECE, USU. As a cutting edge direction, fractional calculus has attracted more and more attractions in control domain. Designed the Fractional Order Adaptive Control (FO-AC) and Fractional Order Periodic Adaptive Learning Control (FO-PALC) for trajectory tracking cogging effect and generalized periodic state-dependent disturbance compensation. From systematic design point of view, proposed some simple and practical tuning methods of the Fractional Order Proportional Derivative (FOPD) controller design and Fractional Order [Proportional Derivative] (FO[PD]) controller design for the position servo motion control system and a class of simplified fractional order systems, which can achieve favorable dynamic performance and robustness. 
(2) As a co-author to write the proposal on Applied Fractional Calculus (AFC) of the Research Experiences for Undergraduates (REU) program, which is sponsored by the National Science Foundation (NSF) of the Federal Government of America.
(3) Made an intensive study on the Periodic Adaptive Learning Control of trajectory tracking cogging effect and generalized periodic state-dependent disturbance compensation for the PMSMor PLSM based on the industrial background and motivation, which contains the First-Order PALCA-High-Order PALC, Dual-High-Order PALC, and Dual-High-Order Dynamic PALC for long-term stability. All the control schemes designed were validated on the experimental benches in the Mechatronics Lab of CSOIS, ECE, USU. A fractional horsepower dynamometer was also developed as a general purpose experiment platform for testing our proposed control methods, which was modified to connect to a Quanser MultiQ4 board in order to control the system through Matlab/Simulink Real-TimeWorkshop (RTW), or connect to LABVIEW board and use the concerned software to realize the Hardware-in-the-Loop prototype.
3. Ph.D Candidate.                                High-Accuracy and High-Powered Servo Drive System Project.
    ASE/SCUT                                          Aug. 2005. – Sep. 2007.

Led a five members group
and developed a suit of high-accuracy and high-powered servo drive system (Servo-ServoPicture / Servo-NoticeServo-Proposal / Servo-ReceivingDocs / Servo-Paper1) cooperating with LOKSHUN Numerical Measurement and Control Equipment Corporation. In this designed servo system, TMS320F2812 DSP which was specially developed for motor control was used as the control kernel of the whole system. APA300 FPGA} was used as the support processor. At the same time, the MITSUBISHI Intelligent Power Module (IPM) PM100RSE060 and Okapi sensor LEM LTSR were used for the switch control and current measurement in the servo drive system. SVPWM Vector Control software scheme was performed and developed on this servo system with our patent, "PMSM Servo Control System Method Based on Rotor and Stator Magnetic Fields Direct-Orthogonalized Vector Control". Compared with the SANYO Servo RS1A05AA under the same condition, the performance of our designed servo drive system can achieve the same as that of the SANYO servo RS1A05AA, but the cost of our designed servo is much cheaper. Furthermore, the Triaxial Linked System was built using our designed drive servo based on the industry background of the cooperation company,  which have been used in the products.  In the triaxial linked system, the S3C2400 (ARM920T) was used as the control system central processor, and both the μcos-II and Linux operating system were performed as the environment of the system software development.
4. Master Candidate.                              Hydrology Automatic Telemetering System Project.
    ASE/SCUT                                             Sep. 2005. – Feb. 2006.

In view of the low level of the Hydrology Automatic Telemetering System (HATS) in China, we developed a HATS  (HATS-Pictures / HATS-Proposal / HATS-Paper / HATS-PPT /  System-PPT ) based on GSM/GPRS which has obtained extensive application in many areas in China. From the systemic design for the remote telemetering station and the base station, to the hardware and software details design, and finally, we performed the real application experimental tests for our designed HATS system in many reservoirs in Qingyuan City, Zhuang Dong Province, China. The analysis results of the experimental data proved that our designed HATS was accurate, convenient and reliable. The key point of our HATS was the design of the remote telemetering station. In order to guarantee the real-time property and enhance the reliability of the remote telemetering station, the real-time operation system μcos-II was adapted to this system, and all the software design was completed based on the μcos-II, including the device drivers development, the TCP/IP protocols encoding, the realizations and application system task design of GSM and GPRS wireless communication. 80c196kc was used as the MCU of this system. The Interpolation Algorithms were performed and developed on this multi-axis linked system.

5. Master Candidate.                               AC Motor Energy Saving Intelligent Control Device Project
    ASE/SCUT                                             Sep. 2004. – Jul. 2005.

Concerned about the nominal power of the AC motor is much bigger than the actual load power sometimes, in order to enhance the power factor of the motor, thereby save power energy, designed a AC Motor Energy Saving Intelligent Control Device (MESICD-Picture / MESICD-Proposal/ MESICD-Instruction / MESICD-Paper MESICD-ImprovementPPT), where the MCU M68HC908GP32 was used to control the flow angles of the Thyristors in three phases, and then regulate the three phases output voltage to the motor. Furthermore, did some research on open-phase protection for the AC motor bearing solid state relay in the power supply circuitry, which made our designed AC motor energy saving intelligent control device more robust and reliable.
