Outline of main research interests

Research interests and activities:

  • The development of advanced control theory and their applications: Significant original contributions have been made in nonlinear control and robust control, particularly in the development of disturbance observer based control techniques (DOBC) for nonlinear systems under disturbance and(or) uncertainty, and model predictive control (MPC) of nonlinear systems. Applications are focused on flight control of helicopters, fixed wing aircraft and spacecraft. 
  • Signal processing: Computer vision, data fusion, tracking with GMTI radar, multiple target tracking, Bayesian estimation, particle filtering techniques, real-time signal processing with the help of domain knowledge/world models.
  • Development of autonomous system technologies: Autopilot, navigation, data and information fusion, collision avoidance, path planning, mission planning, conditional and heath monitoring, situational awareness, decision making under uncertainty, autonomous taxiing, terminal area operation of unmanned aircraft, Advanced Driver Assistance Systems (ADAS),  system integration, and flight tests.    
  • Application of autonomous system technologies: A wide range of applications of autonomous system/vehicle technologies have been researched particularly in agriculture and environment monitoring. Water management, weed management, pest and disease monitoring, chemical, biological and radiation substance monitoring/search, communication relay with UAVs, and disaster and emergency managements.
  • Safety and verification and validation of autonomous system technologies: Safety is embedded in the core heart of our research particularly for the operation of autonomous vehicles in public domains. Research in this area consists of two directions: the development of safety functions for autonomous vehicles or other vehicles,  and the development of efficient verification and validation technologies for autonomous functions. For the former, active contingence management such as autonomous forced landing techniques has been developed with BAE Systems. For the latter, automatic worst case search and reachability analysis are main techniques that have been developed.

Sustainable Agriculture in China, UK and other countries    

Recently Wen-Hua has developed a strong interest in applying autonomous system technologies in tacking global challenges such as food security and environment protection. Wen-Hua is now leading an international team working on the development of remote sensing for agriculture applications using unmanned aircraft systems. The team consists of researchers from Loughborough, Manchester, Cranfield and East Mailing Research in the UK, and BUAA, Beijing Aerospace Automatic Control Institute and other partners from China.  A major ongoing project in this area has been jointly funded by the UK and China government  through the Newton Fund in UK Research Council (£1M) and the international research collaboration programme of the National Science Foundation of China (3M RBM).  The project is aimed to support precision agriculture in China so to reduce the use of resources (e.g. water, land) and the environment impact of using fertiliser, pesticide and herbicides by providing real-time site specific information for treatment and management using remote sensing technologies. It is expected that the similar technologies can be used in other countries and for other applications such as wild animal monitoring and environment protection.
