Research Activities
Wenjian’s current research is focus on process instrumentation, control and optimization with applications to energy and environmental areas:
Ejector
based air-conditioner:
Development of high efficiency air-conditioning system using low temperature
heat source and ejector-compressor cycle for automobile and food processing
industries. The R&D topics includes: mechanical design, modelling
and control system development and performance test. He is collaborating with
Professors Zhiyuan Liu of Harbin Institute of
Technology, Yanzhong Li of Xi’an Jiaotong University and Xiaowei
Fan of Pingyuan Institute of
Technology of
Wind Turbine Control: Development of variable speed wind turbine
control system using multi-model supervisory control technology previously
developed for HVAC control systems. The R&D topics includes: modelling, parameter identification, control system
development and performance test.
Energy
management, optimization and control system: Integrated Energy Management, Control and
Optimization system (EMOCS) for building HVAC processes. This project is to
improve the system already developed under industry funded project of
“Development of Optimization Technologies for Building HVAC Systems”. He is
collaborating with Centre for Energy Efficiency of Shandong
University of China on this project.
Portable
COD meter: Portable
real-time Chemical Oxygen demand sensor by electrochemical analysis method.
This is a cooperative project with Purechem Onyx Pte Ltd which including: methodology study, software and
hardware design, interface and communication protocol development.
Process
auto-tuning software package: For all industry control schemes including: identification (single
open-loop/closed-loop, multivariable open-loop/closed loop), PID parameter
tuning (single loop, large time delay, inverse response, open loop unstable,
cascade, feedback/feedforward, multiloop),
and effective control loop configuration method for decentralized control. He
is collaborating with Professors Shaoyuan
Li and Weidong Zhang of Shanghai Jiaotong University of
Hand held
PID auto-tuner: A
field control engineer tool for on-site tuning PID parameters without
interference with the normal process operation. The third prototype is
currently been fabricated to make the instrument more powerful.
