Finite-Control-Set Model Predictive Control for DFIG Wind Turbines
IEEE Transactions on Automation Science and Engineering, 2018This paper presents a time efficient finite-control-set model predictive control (FCS-MPC) scheme for the doubly fed induction generator system. In this scheme, the switching states of the rotor side converter are directly taken as control inputs. This way, the optimized control action can be directly applied to the converter.

Finite control set model predictive control of a Stacked Multicell Converter
IECON 2015 - 41st Annual Conference of the IEEE Industrial Electronics Society, 2015Multilevel converters are an attractive alternative for medium voltage applications. The Stacked Multicell Converter (SMC), in particular, is a multilevel converter that allows to increase the output voltage level compared with the classical Flying Capacitor Converter, while decreasing the stored energy in the converter.

Sensorless finite control set predictive current control for an induction machine
2015 IEEE International Conference on Information and Automation, 2015Finite control set predictive current control is a new solution for control of electrical drive systems. The system has a straightforward control scheme. Current errors between the reference and the predictive values are evaluated in cost function. In this paper, an extended Kalman filter is used for predictive current control to realize sensorless ...

Finite Control Set-Model Predictive Speed Control with a Voltage Smoother
IECON 2018 - 44th Annual Conference of the IEEE Industrial Electronics Society, 2018In this study, direct speed control based on a finite control set-model predictive speed control (FCS-MPSC)with a voltage smoother is presented to reduce current ripple. In the proposed control scheme, the controller predicts the future current and speed states with a finite set of smoothed voltages and outputs the optimal smoothed voltage by using ...

A Simplified Finite-Control-Set Model-Predictive Control for Power Converters
IEEE Transactions on Industrial Informatics, 2014Finite-control-set model-predictive control (FCS-MPC) requires a large amount of calculation, which is an obstacle for its application. However, compared with the classical linear control algorithm, FCS-MPC requires a shorter control loop cycle time to reach the same control performance.

Finite Control Set - Model Predictive Control applied to multicell rectifiers
IECON 2013 - 39th Annual Conference of the IEEE Industrial Electronics Society, 2013Multi-cell converters allow the use of AC motor drives for medium and high voltage level applications using low voltage semiconductors. This type of converter has a multi-pulse transformer which performs the cancellation of the low frequency harmonics generated by the three-phase diode rectifiers.

Finite dimensional attainable sets for stochastic control systems
Advances in Applied Probability, 1975Letx t u (ω) be a stochastic control system on the probability space (Ω, ℱ,P) intoRn. We say that the pointx∈Rn is (e, δ) attainable at timet if there exists an admissible controlu such thatPxo{x t u (ω)∈S∈(x)}≥δ, wherex0(ω)=x0, e≥0, 1≥δ≥0, andS∈(x) is the closed Euclidean e-ball inRn centered atx. We define the attainable setA ɛ δ (t) to be the set of

Complexity of controlled bad sequences over finite sets of Nd
Proceedings of the 35th Annual ACM/IEEE Symposium on Logic in Computer Science, 2020We provide upper and lower bounds for the length of controlled bad sequences over the majoring and the minoring orderings of finite sets of Nd. The results are obtained by bounding the length of such sequences by functions from the Cichon hierarchy. This allows us to translate these results to bounds over the fast-growing complexity classes.

IEEE Transactions on Industrial Informatics, 2018
This paper presents a comparative study of two predictive speed control schemes for induction machine (IM) in terms of their design and performance. The first control scheme is finite control set-model predictive control (FCS-MPC) with modulation control and the second control scheme is continuous control set-model predictive control (CCS-MPC) with ...

A Robust Finite Control Set Applied to the DFIG Power Control
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2018This paper proposes a robust finite control set for doubly-fed induction generator power control. In this way, the proposed robust finite control has two components of the predicted rotor voltage. The first term calculates the voltage considering the rotor current references and the second term is designed considering the mistakes due to parameters ...
