The design of decentralised robust load frequency control for interconnected multi-area power systems is studied in this paper. It is shown that although the design can be naturally formulated as a large-scale system decentralised control problem, it...

Integrating Petri Nets and hybrid heuristic search for the scheduling of FMS (2001)
Journal Article
Reyes, A., Yu, H., Kelleher, G., & Lloyd, S. (2002). Integrating Petri Nets and hybrid heuristic search for the scheduling of FMS. Computers in Industry, 47(1), 123-138. https://doi.org/10.1016/s0166-3615%2801%2900124-5

This paper studies modelling and scheduling of Flexible Manufacturing Systems (FMS) using Petri Nets (PNs) and Artificial Intelligence (AI) based on heuristic search methods. A subclass of PNs, Buffer nets or B-nets is obtained by the systematic synt... Read More about Integrating Petri Nets and hybrid heuristic search for the scheduling of FMS.

Robust Combined Adaptive and Variable Structure Adaptive Control of Robot Manipulators (1998)
Journal Article
Yu, H. (1998). Robust Combined Adaptive and Variable Structure Adaptive Control of Robot Manipulators. Robotica, 16(6), 623-650. https://doi.org/10.1017/s0263574798000563

The paper addresses the robust adaptive control problem of robot manipulators. The dynamic equations of robot manipulators and their fundamental properties that facilitate analysis and control system design are first reviewed. Then the direct, indire...

Variable structure adaptive control of robot manipulators (1997)
Journal Article
Yu, H., & Lloyd, S. (1997). Variable structure adaptive control of robot manipulators. IET Control Theory and Applications, 144(2), 167-176. https://doi.org/10.1049/ip-cta%3A19970803

The two main problems with variable-structure control are control input chattering and the assumption of known parameter uncertainty bounds, the second of which is studied. The robustness of a recently proposed variable-structure control approach wit... Read More about Variable structure adaptive control of robot manipulators.

Combined direct and indirect adaptive control of constrained robots (1997)
Journal Article
Yu, H., & Lloyd, S. (1997). Combined direct and indirect adaptive control of constrained robots. International Journal of Control, 68(5), 955-970. https://doi.org/10.1080/002071797223154

The force tracking error is dependent on both the position tracking error and the estimated parameter error so that, in constrained adaptive robot control, the convergence of the estimated parameter error becomes more important than in unconstrained...
