[Lecture Notes in Networks and Systems] Renewable Energy for Smart and Sustainable Cities Volume 62 (Artificial Intelligence in Renewable Energetic Systems) || Sliding Mode Control of DFIG Driven by Wind Turbine with SVM Inverter
摘要: In this paper, a direct Sliding Mode Control (SMC) of Doubly Fed Induction Generator (DFIG) driven by wind turbine with Space Vector Modulation (SVM) inverter is presented. The SMC is used to track the stator active and reactive power their references. The SVM inverter is used to improve the quality of the energy generated by DFIG which allows the minimizing of stator current harmonics and wide linear modulation range. Simulation results show that the proposed control give good performance and good quality of the energy where the THD of the stator current of the DFIG has small value.

Sliding mode control of photoelectric tracking platform based on the inverse system method
摘要: In order to improve the photoelectric tracking platform tracking performance, an integral sliding mode control strategy based on inverse system decoupling method is proposed. The electromechanical dynamic model is established based on multi-body system theory and Newton-Euler method. The coupled multi-input multi-output (MIMO) nonlinear system is transformed into two pseudo-linear single-input single-output (SISO) subsystems based on the inverse system method. An integral sliding mode control scheme is designed for the decoupled pseudo-linear system. In order to eliminate system chattering phenomenon caused by traditional sign function in sliding-mode controller, the sign function is replaced by the Sigmoid function. Simulation results show that the proposed decoupling method and the control strategy can restrain the influences of internal coupling and disturbance effectively, and has better robustness and higher tracking accuracy.

Robust precision motion control of piezoelectric actuators using fast nonsingular terminal sliding mode with time delay estimation
摘要: Background: Piezoelectric actuators are widely used in many micro/nano-manipulation applications, but their positioning accuracy are badly affected by their inherent nonlinear hysteresis and creep. To solve this problem, this paper presents a new robust motion-control method for piezoelectric actuators with fast nonsingular terminal sliding mode based on time delay estimation. Method: The proposed controller needs no detailed information about the hysteresis and other nonlinearities of the system, leading to a simple and model-free characteristic due to the time delay estimation and ensures fast convergence and high tracking accuracy thanks to the nonsingular terminal sliding-mode surface and fast terminal sliding mode -type reaching law. A robust exact differentiator is adopted to estimate the velocity and accelerationinformation online, and it overcomes the limitation of only available position measurements. The finite-time convergence and stability of the closed-loop system are proved by using a Lyapunov function. Results: Experimental results show that the proposed control strategy has faster convergence and higher tracking precision compared with a traditional time delay control. Conclusion: The proposed control strategy can be widely used as an effective control method for high-precision motion control of piezoelectric actuators.

摘要: In this work, a hybrid solar-battery feeding system is proposed to achieve a constant output power on a fixed-wing Unmanned Aerial Vehicle-UAV. Firstly, a single and hybrid power source configurations for long endurance UAV applications are exposed. Thus, a solar-battery based feeding system with a suitable energy management is proposed. Furthermore, a Maximum Power Point Tracking (MPPT) technique is selected to achieve the maximum efficiency of the solar photovoltaic (PV) array. Besides, Sliding-Mode Control (SMC) is implemented on a cascade control scheme in order to achieve a suitable energy conversion. Finally, the hybrid feeding system performance is analyzed for different solar radiation and load profiles remarking proper dynamic and steady-state responses.

摘要: Control strategy basing on sliding mode theory has a unique place in power electronics field in order to guarantee robust, efficiency and reliable control. This paper presents Space Vector based Hysteresis Current Controller (SV-HCC) algorithm used connected photovoltaic source. This control is carried out basing on the theory of variable-structure system. So, a control signals, presented in (dq) synchronous reference-frame, have been analyzed basing on a well defined attractive condition in order to reach the sliding surfaces. To keep these control signals on their corresponding sliding surfaces, an invariance conditions must be satisfied. Simulation results are illustrated to present the high performance and the robustness of SV-HCC. Excremental tests are also illustrated to show the reliable of the developed control.
