Classical model based predictive control for single-phase cascade H-bridge multilevel STATCOM generates a variable switching frequency that produces high frequency harmonics and high stress on the power semiconductor devices. To solve these issues, in this paper is proposed a predictive control strategy operating at fixed switching frequency. The method includes a modulation stage in the predictive controller. Simulation results show increased performance of the proposed control method in terms of current ripple and total harmonic distortion.

The control of linear interconnected systems has become an area of significant research thanks to its various applications. This paper proposes the determination of a predictive control strategy for linear processes. The main idea is to formulate an approach for designing the model based predictive control (MBPC) for large scale linear interconnected systems. This approach consists on associating a sub-MBPC for each sub-system. In fact, this works introduces a strategy to solve problems caused by the interactions among subsystems. The robustness and efficiency of the proposed approach are illustrated through numerical example.

In this article a control strategy for an induction machine (IM) based electric variable transmission (EVT) for hybrid electrical vehicles (HEV) is presented. Such electrical machines consists out of two rotors resulting in a power split and a decoupling of the internal combustion engine (ICE) speed and wheel speed. The proposed control method relies on a finite-set model based predictive control (FS-MBPC) algorithm to steer the torque of both rotors as well as the flux levelwithin the machine. The advantage of this controller is the inherent feature of field weakening and strong reduction of Joule losses as a result of the optimisation routines within this controller using a cost function. As the focus of this paper is on the control method, simulation runs in Matlab/Simulink are performed to asses the feasibility and effectiveness of the proposed control method.

model based predictive control (MPC) is an interesting approach due to its ability to consider the constraints of the controlled system and easily adapt to the future reference changes. In this paper, a novel robust MPC controller is presented, which considers the effect of the Tool Center Point (TCP) estimation errors and the model uncertainties of the mechanical structure. In order to show its effectiveness, its application to the 5R parallel manipulator is detailed. Simulation validation is provided to demonstrate that the proposed approach can exploit all the theoretical capabilities of the mechatronic system. © Springer Science+Business Media Dordrecht 2014.

学位级别：Ph.D.

This thesis builds upon recent studies focusing on modeling, operation, and control of high temperature gas cooled reactors. A computer model was developed, based on mass, energy, and momentum balances of control volumes throughout the plant. Several simulations of the plant behavior were conducted and their results were compared with those from the literature. Proportional control was combined with optimal control to form a time varying, adjustable gain predictive controller which adjusts the proportional gains during transients. The controller was designed to utilize control rod motions and bypass control valves to maintain desired plant conditions. An optimization scheme was introduced to efficiently solve the optimization problem formulated as part of the predictive controller operation. Several additional transients were run to examine the full plant controller performance. Multiple predictive controllers were designed and their performance was compared with a proportional controller throughout each transient. The predictive controller results confirmed the importance of proper selection of the optimal controller parameters, in particular the controller time step size and the horizon time. The well-designed proportional controllers clearly demonstrated improvements in plant performance during short time scale transients, namely a loss of secondary heat transfer transient and a step change in desired power transient. Results from long time scale transients demonstrated the capabilities of the proposed bypass control system to control electrical power production without the need for storage vessels.

In this paper model based predictive control (MPC) is used for torque control of three phase Induction Motor. In conventional torque control methods, a switching table is used for switching of the inverter in order to keep the torque and flux within the limits. MPC can be used to reduce the switching frequency of the inverter along with better torque and flux response. Torque and flux is predicted for next few samples and most suitable sequence is selected which causes least inverter switching. Receding horizon policy is applied in which the first switching state of the selected sequence is applied to inverter. MPC requires complex computations which limits its application. Finally a Branch and Bound algorithm is applied in order to improve its computational cost.

The computational time in a nonlinear model-based predictive control (NMPC) depends on several factors. For its implementation, very short execution times are required, which translates into specialized and robust computational capabilities. These capabilities can be evaluated using external servers and Single Board Computers (SBCs), small in size, but with important computational features. The present work evaluated the computational time required in the implementation of a remote NMPC for three different models of a distillation column using the Python Gekko library on a Raspberry PI 3B+ board, and using an Aspen Plus Dynamic simulation as a plant through Open Platform Communication (OPC). In total, 9 cases involving between 2229 and 5109 state variables were evaluated, finding that, in all cases, the time needed to solve the NMPC was less than 30 s, with a CPU consumption of less than 50%.

A model based predictive direct power control with finite set of control variables for the three phase four switch-based converter B4 connected to an unbalanced grid is introduced. The instantaneous active and non-active powers are outputs of the controlled system. The alternative instantaneous non-active power theory is used that preserves harmonic free grid currents not only for a symmetrical but also unsymmetrical voltage system. Simulation results for the L grid filter are presented and analyzed.

The main goal of this work is to design Battery Storage Management solutions for Smart Grids with multiple interconnected microgrids, or local power generation units, using a distributed model predictive control approach. In order to know how much energy should be stored, sold or bought, a model predictive control policy computes the minimum of a cost function that minimizes the net revenue. The solution also encourages some level of storage. The alternating direction method of multipliers computes the proposed distributed model predictive control solution, considering that each system is directly interconnected with its neighbors. The distributed predictive control algorithm is described and tested in simulations.

control of a non-linear multivariable system in non-minimum phase by using a neural predictive controller

REVISTA IBEROAMERICANA DE AUTOMATICA E INFORMATICA INDUSTRIAL 2023年第1期20卷 32-43页

In this paper, a Neural predictive controller (ANN-MPC) is proposed to control a nonlinear quadruple tank system, which is complex to control due to the nonlincarily of its valves and the interaction between its controlled variables. In addition, the problem is aggravated since the process presents a transient response with inverse dynamics due to being in a non-minimum phase. The ANN-MPC employs a modular artificial neural network framework and the Levcnbcrg-Marquardt training algorithm to more accurately and quickly estimate nonlinear process outputs and avoid model overfitting. Operational data was generated from the plant to train the neural network using Matlab. The performance of the ANN-MPC under reference changes was tested and compared with a linear MPC and a non-linear MPC. The simulation results showed that the ANN-MPC produced a shorter settling time than the linear MPC and generated RMSE values of the outputs similar to those of the NMPC In addition, the computation time required to calculate the optimal control variable was reduced compared to the NMPC. © 2023 Universitat Politecnica de Valencia.
