Finite-Time Observer-Based Formation Tracking With Application to Omnidirectional Robots
No full textThe challenging problem of robust formation control pertaining to omnidirectional robots with model uncertainty and actuator saturation is comprehensively investigated in this article. First, an observer-based formation controller is designed to ensure the semiglobal uniform ultimate boundedness of the system’s formation tracking error. Then, both global stability and practical finite-time stability are achieved to ascertain the practicality of the observer design. Apart from restricting the control input amplitude, we also investigate the reverse effect caused by saturated and coupled control input. As such, an adaptive compensator is formulated to attenuate the state oscillation caused by the reverse effect. Both numerical simulations and hardware-in-the-loop experiments are carried out to illustrate and evaluate the effectiveness and potentials of the proposed new techniques for real-world applications.Yang Fei, Peng Shi, Chee Peng Lim, and Xin Yua

Dynamic response of an Offshore wind turbine using linear (LIM) and non-linear (NLIM) environmental interaction models: A Parametric study
No full textThe present state-of-the-art modelling tools (such as FAST, BLADED) used for modelling an offshore wind turbine (OWT) are too detailed and computationally expensive. These tools are required only at detailed design stages of a project. For the preliminary phase, however, a much simpler (yet reliable) 3D model can improve and speedup the design process. Therefore, the aim of this thesis was to develop two different finite element models of an offshore wind turbine and compare their dynamic responses. In order to assess the extent of non-linearities in the environmental interactions arising due to structural motions, one model included the non-linear models of soil, hydrodynamic and aerodynamic loads (called NLIM henceforth) while the other used linearized expressions for modelling them (called LIM henceforth). The soil was modelled as a series of non-linear (and linear) elastic springs using p-y curves. The conventionally used Morison's equation was compared with MacCamy and Fuchs' equation for modelling the hydrodynamic loads on a large diameter pile. It was found that the MacCamy and Fuchs' equation is a better way of modelling the hydrodynamic loads on submerged cylinders than Morison's equation as it takes the wave diffraction effects into account. Several load cases were defined and the models were subjected to these load cases to check whether they are able to capture the physical behaviour of the OWT. The modal decomposition technique was used for reducing simulation time. It was found that the model(s) adequately captured the physical behaviour of the OWT till a wind speed of 20 m/s. Its side-side plane physical behaviour needs further investigation for a constant wind speed of 24 m/s. The LIM and the NLIM compared well for most load cases. For the side-side plane responses, however, the LIM developed a phase lag. A strong coupling was found between the motions (rotations) in fore-aft plane and the motions about the yaw axis. The structural velocities were found to be very small to influence hydrodynamic drag terms. Also, the defections of the pile in the soil were found to be too small suggesting that p-y curves do not capture the non-linear behaviour of soil accurately. Finally, a damping matrix resulting from the linearised aerodynamic forces was used for calculating the modal damping ratios related to different modes. The results were compared to the literature, with addition of side-side and yaw damping.Mechanical, Maritime and Materials EngineeringHydraulic EngineeringOffshore Engineerin
A new unity-gain 5-level active neutral-point-clamped (UG-5L-ANPC) inverter
No full textThe active neutral-point-clamped (ANPC) inverter is a popular multilevel inverter for various industry applications. In a recent attempt, an improved topology that integrates a flying capacitor to enhance the voltage gain from half to unity has been presented [11]. Retaining the benefit of unity-gain, this paper proposes a new ANPC topology with two improvements. Firstly, the voltage stress of the flying capacitor is reduced by half. Secondly, the charging of the flying capacitor at 0 level is made possible to achieve uniform charging over the power cycle. Comprehensive analysis is presented and experimental results of a prototype are presented for validation. Finally, the extension of the topology with increased number of output voltage levels generation is briefly discussed
