Energy management system (EMS) is important for the planning and operation of power system as the power generation must supply enough energy for load with the minimum operating cost. This paper presents nonlinear MPC to dispatch power generation within the limitation of the power system. The objectives are to improve EMS by considering AC optimal power flow and provide a dispatch strategy to reduce total operating cost (TOC). To realize the proposed nonlinear MPC, we consider the power plant model of Mae Hong Son in the northern part of Thailand. Load data and power generation profile are utilized as the inputs to MPC of EMS to minimize TOC for one day ahead. In this work, the optimal power flow is incorporated as the second order cone constraints. It is shown that EMS with optimal power flow can operate within the rated voltage for all buses. When comparing the results in normal mode with one-shot optimization, the proposed MPC can reduce the TOC by 1.72% in the rainy season. © 2021 IEEE.

Evaluation Method and Workbench for APC Strategies

IFAC Proceedings Volumes 2004年第1期37卷 809-814页

作者： G. Reinig B. Mahn Ruhr University of Bochum Faculty of Mechanical Engineering Chair of Control Engineering

The large number of various advanced control strategies (e.g. Model Predictive control. Neural Networks or Fuzzy control) and the lack of a practically usable selection methodology make it very difficult to choose an appropriate strategy for a given plant. In order to support the selection of proper control strategies and products a set of relevant evaluation criteria is developed. A flexible and expandable test environment (workbench) is created aiming at a controller evaluation considering these criteria. The evaluation approach and workbench are demonstrated for PID based and commercial Model Predictive controllers at some typical process units and plants.

Water loss is a global problem. Water loss in leakages in water distribution systems (WDSs) can be significantly reduced as pressures at outlets of pumping stations are optimized. Due to the introduction of binary variables for describing on/off operations of pumps, the optimal pressure management is formulated as a large-scale mixed integer nonlinear programming (MINLP) problem which is extremely difficult to be solved by MINLP algorithms. Many studies have employed meta-heuristic algorithms to solve such the MINLP problem, but only applied for small-scale networks and it took an expensive computation time. This paper develops an efficient formulation of MINLP for optimal pressure managing problem. It is due to the fact that the large-scale MINLP can be decomposed into small-scaled MINLPs, hence it can be solved efficiently by MINLP solvers based gradient methods in an reasonable computation time. To demonstrate the efficiency of our solution approach, the real-world water distribution systems in Thainguyen city in Vietnam will be considered for optimization of pressure management. The resulted pumping schedules lead to higher reduction of excessive pressures and water leakage amounts in comparison with those by the current pumping schedule. © Springer International Publishing AG 2018.

Purpose: Our aim is to apply a rehabilitation device in household. The development of a rehabilitation device is based on the principle of the exoskeleton. Method: We describe the mechatronic shoe developed as result of research in 7FP-project SMILING with application in geriatric rehabilitation medicine. The overall objective is to develop and construct an advanced prototype of a wearable non-invasive computerized miniature rehabilitation device for mechanical chaotic perturbations of gait pattern in order to counteract and prevent tendencies to fall. The main tasks were to develop perturbation algorithms fitted to suit individual user's specific needs and to implement a training system to be used in rehabilitation, health care, and fitness centers for a reorganization of the rehabilitation process in ageing. The SMILING shoe is a complex mechatronical system that requires interaction of various sensors data, mechanical components, and human activity. Two different designs were developed: STRATH and TUKE. Both left and right shoes are equipped with 4 mechanical units driven by DC-motors. Two are in the front and two are in the back side. In generally, mechanisms change the height after each or several steps, and in such way they change inclinations of the shoes sole in two planes - frontal and sagittal. The SMILING shoe is worn on a standard shoe used by user. The user has to react to changes of the shoe inclinations to stay balanced when walking while completing specific tasks. Beside the SMILING shoe, we are working on the development of a rehabilitation robot for upper limbs using pneumatic air muscles. The robot is designed on the principle of exoskeleton and is intended for the rehabilitation of the shoulder and elbow;the device has 4 degrees of freedom and uses an antagonistic pneumatic air muscles arrangement. Results & Discussion: In the testing phase, 4 pairs of the SMILING shoes produced by the University of Strathclyde were tested in clinical trials with

Hydrothermal vent areas are unique ecosystems with high productivity and high biodiversity that are subject to ongoing research. Hydrothermal vents form in areas with increased magmatic activity where superheated, mineral rich water leaks from the seafloor. Due to the rapid cooling of the water the metal sulfides precipitate and form a black or white plume that can be sensed several hundred meters away from the vent source. Finding and reliably following such plumes with autonomous underwater vehicles (AUVs) is a challenging task since the plume does not have a smooth concentration gradient but lots of local patches due to the turbulent particle flow. This paper presents an algorithm that combines biology inspired chemotaxis with Unscented Kalman filter (UKF) based extremum seeking control (ESC). The effectiveness is demonstrated by a simulation of a physics-based AUV model in a turbulent 3D Plume model. © 2022 Elsevier B.V.. All rights reserved.

The paper deals with the description of block-oriented nonlinear dynamic systems having multisegment piecewise-linear nonlinearities and with their identification using the Wiener model. A new form of multisegment nonlinearity representation and multiple application of a decomposition technique provides a special form of Wiener model with the minimum number of parameters. The model is linear in all the parameters to be estimated and is used in the proposed identification method. An illustrative example is included. © 2003 IFAC.

The bifurcation behaviors of coupled Andronov-Hopf oscillators is analyzed. For this, an analytic solution of the bifurcation point of two linear, static coupled Andronov-Hopf oscillators is provided. This solution is rearranged so that the bifurcation can be interpreted geometrically by maximizing the area of an triangle defined by the system parameters. This geometric interpretation serves as the basis to address a network of linear, static coupled Andronov-Hopf oscillators, where a rather simple solution for the bifurcation point can be determined depending on a simple tree topology. With this, implications about the synchronization of this class of networks can be deduced. © 2022 Elsevier B.V.. All rights reserved.

The main idea of this project is to simulate the thermal construction responses in dependence on changing boundary conditions. In order to predict environmental temperature precisely a model of one room has been developed and implemented in COMSOL Multiphysics. A finite element model was developed in 3D coordinates in order to achieve illustration of an air and an energy movement and to simulate the transient process in the walls in [7]. Notwithstanding, this model was not accurate enough for application in building conditions. Main goal of this paper is in updating current model to get results with sufficient accuracy. Temperature course of the model is analyzed and compared to the experimentally measured temperature data. © 2011 IEEE.

In this study, generalized self-tuning regulator (STR) based on support vector regression (SVR) which was previously introduced [1] is deployed to control a continuously stirred tank reactor (CSTR) system. The parameters of the Fuzzy PI D controller utilized in the controller block are tuned via SVR based parameter estimator and system model blocks. The performance of the controller has been evaluated by simulations carried out on the CSTR system. © 2017 EMO (Turkish Chamber of Electrical Enginners).
