Harmonic distortion introduced by nonlinear loads in the electric system is hard to measure and anticipate, and the effects are harmful to other loads. To compensate these drawbacks, usually active power filters are used, but their performance depends on the method used to generate the reference current, and on the parameters of the filter. This paper presents a new Matlab Simulink control block which allows the rapid tuning of filter's parameters, enables the selection of one of the six most usual control algorithms, and also can generate code for future implementation on microcontrollers.

First we show that continuous piecewise-affine systems are equivalent to max-minplus-scaling systems (i.e., systems that can be modeled using maximization, minimization, addition and scalar multiplication). Next, we consider model predictive control for these systems. In general, this leads to nonlinear non-convex optimization problems. However, we present a method based on canonical forms for max-min-plus-scaling functions to solve these optimization problems in a more efficient way than by just applying nonlinear optimization as was done in previous research.

Electric vehicles (EVs) have gained popularity in recent years due to their environmental friendliness and low operating costs. However, the inconvenience of traditional EV charging methods has been a major barrier to widespread adoption. In this paper, we propose a smart wireless EV charging system that uses the integration of Internet of Things (IoT) and Radio Frequency Identification (RFID) technologies to improve the convenience and efficiency of EV charging. The system allows for automatic charging without the need for physical contact between the charging pad and the EV, thanks to the use of wireless power transfer technology. The system is also equipped with real-time monitoring and control capabilities, allowing users to check the status of their EVs and charging sessions via a mobile app. Additionally, RFID technology is used to enable secure and seamless authentication of the EV and the user. The proposed system has been simulated and evaluated in terms of its performance and energy efficiency, and the results show promising performance. This paper presents a step towards a smarter and more sustainable transportation system. © 2023 IEEE.

Implementation of Simulink controller design on Iris+ quadrotor

作者： Wei Zhong Fum US Naval Postgraduate School

学位级别：硕士

The thesis has two primary objectives. First, it develops a high-fidelity 6DOF flight dynamics model of a multi-copter UAV, and uses it for the design and implementation of the linear attitude controller onboard of an industrial quadcopter; both steps are implemented in Simulink. Second, it leverages the weakly joint efforts of MathWorks and the open-source community to build a software setup that enables rapid control software prototyping. This software architecture enables control system design and integration without the need for proficiency in embedded coding that typically utilizes high-level programming languages like C/C++. The higher impact of the dual objective is in advancing methods and tools of verifiable control system design and the embedded code generation that simplifies the V&V process. The 3DR Iris+ quadrotor, equipped with PX4 "Pixhawk" autopilot, is selected as the primary prototyping platform. The autopilot allows for the real-time execution of an application (attitude controller) that is auto- generated from MatLab/Simulink. This makes the Iris+ quadrotor an ideal platform for rapid flight control prototyping by using MathWork's auto code generation capability. Ultimately, the developed setup represents a convenient research and development tool that natively bridges the gap between the safety-critical flight control science and flight experimentation technology by "eliminating" the error-prone manual coding of embedded microcontrollers.

The present work deals with diminishing the effects of wireless communication latency in time-sensitive networks. It takes advantage of modern approaches that offer bounded latency and it focuses on methods to cope with the nondeterministic delays introduced by communication *** observer-predictor scheme module is designed and added in the control loop to prevent the performance degradation when a wireless network is introduced. The goal is to allow the use of same controllers used in wired networks. This module may exploit information provided by the wireless communication devices, such as expected latency, timestamp, and time synchronization along the *** proposed module allows the controller to have a performance similar as when in a wired network. This enables wireless networked control in systems with low time constants (i.e. timesensitive).Lab experiments are presented in real-time to illustrate the observer-predictor scheme module proposed. Finally, the conclusions and future work are presented.

The design of nonlinear multivariate control systems from state dependent linear models

引用

Journal of Fluids Engineering, Transactions of the ASME 1966年第2期88卷 355-361页

作者： Fertik, H.A. Schoeffler, J.D. Systems Research Center Case Institute of Technology Cleveland OH United States

A technique is presented for the design of a continuous nonlinear multi-variable control algorithm from a set of simple, linear control models. The coefficients of the linear control models are dependent on the steady state operating point. The technique makes use of line integration and the method of least squares to bridge the gap between the sets of linear coefficients and the continuous nonlinear functions of the nonlinear algorithm. In general, the nonlinear control algorithm is nonunique. The method permits the extension of linear design procedures to the design of nonlinear control systems. It can be used to design a control system for a nonlinear process to maintain the dynamics of the entire system invariant with respect to changes in the operating point. © 1966 by ASME.

Many automotive engine models exist for the development of control algorithms. These models should include the important lags and delays which can affect the response of the overall controlled system. One of the most important, and most difficult parts of the engine to estimate is the fuel delivery model, from when the demand for fuel is calculated to intake valve closing. This peeper describes procedures for estimating the parameters of a fuel delivery model, and provides experimental results using these techniques.

The evolving technologies regarding Unmanned Aerial Vehicles (UAVs) have led to their extended applicability in diverse domains, including surveillance, commerce, military, and smart electric grid monitoring. Modern UAV avionics enable precise aircraft operations through autonomous navigation, obstacle identification, and collision prevention. The structures of avionics are generally complex, and thorough hierarchies and intricate connections exist in between. For a comprehensive understanding of a UAV design, this paper aims to assess and critically review the purpose-classified electronics hardware inside UAVs, each with the corresponding performance metrics thoroughly analyzed. This review includes an exploration of different algorithms used for data processing, flight control, surveillance, navigation, protection, and communication. Consequently, this paper enriches the knowledge base of UAVs, offering an informative background on various UAV design processes, particularly those related to electric smart grid applications. As a future work recommendation, an actual relevant project is openly discussed.

A Proportional-Integral controller for Resistance Spot Welding Using Nugget Expansion

JOURNAL OF DYNAMIC SYSTEMS MEASUREMENT AND control-TRANSACTIONS OF THE ASME 1989年第2期111卷 332-336页

作者： Chang, H. S. Cho, Y. J. Choi, S. G. Cho, H. S. Myong Ji Univ Dept Engn Mech Yongin Kyung Gi South Korea Daewoo Shipbldg & Heavy Machinery LTD Ok Po Kyungnam South Korea Hyundai Elect Ind Co LTD Seoul South Korea Korea Adv Inst Sci & Technol Dept Prod Engn Seoul 131 South Korea

An electrode wear has been found to cause considerable quality variation in the process of resistance spot welding. This paper presents a study on the electrode wear growth and develops a microprocessor-based feedback controller that can compensate weld quality variation due to electrode deterioration. The controller developed in this study utilizes a PI control algorithm, incorporating the electrode movement as a feedback signal. A series of experiments was performed to clarify the wear growth phenomenon and to evaluate the performance of the controller. The experimental results show that the electrode wear can significantly cause quality deterioration, but this can be effectively compensated via application of this proposed control technique.
