Special Issue Information

Dear Colleagues,

Electrical drives possess a lot of advantages. As compared to other sources, electrical energy is easy to transport and can be environmentally friendly (when from renewable sources). Modern electrical drives convert energy with high efficiency and have flexible control characteristics. They offer a wide range of speed, torque, and power operation. Furthermore, in general, they can serve as an electrical generator.

The first electrical drives were built in the 19th century. Over time, new constructions appeared. Recently, the topic of modern electrical drives has encompassed many different areas, such as electrical machines, power electronics, control theory, real time control, mechanical systems, modeling, and sensors.

With the growing demand for high-performance electrical drives, the problem of their efficient, robust, precise, and fault-tolerant control is a popular target for many universities and industrial researchers. Accurate control of electrical drives is a crucial point in different types of industry, starting from high-power drives evident in mining and petrochemical areas, through medium (automotive industries, robot arm drives, CNC machines) and small power drives (actuators), ending on MEMS, etc.

In this Special Issue, the topics related to trends, problems, and challenges linked to design and exploitation will be presented. Papers in (but not limited to) the following scope are welcome:

Control strategies for different types of electrical motors (DC, ACIM, PMSM, synRM, SRM, etc.);
Sensor-less control of electrical drives. Estimation of the non-measurable states and parameters;
Application of advanced control methodologies (fuzzy, neural, robust, predictive etc.) for high performance control of electrical drives;
Control of complex mechatronic systems taking into account the mechanical part of the system;
Diagnosis, monitoring and prognosis in electrical drives;
Fault-tolerant control of electrical drives;

Drives and renewable energy systems. Novel topologies of the power converters dedicated to electrical drives.

Robust Speed Control of Uncertain Two-Mass System

by Karol Wróbel, Kacper Śleszycki, Amanuel Haftu Kahsay, Krzysztof Szabat and Seiichiro Katsura

Abstract

The main purpose of this work is to present a robust speed control structure for a two-mass system. The tested system consists of a PI controller with two additional feedback. The coefficients of the control system are selected using a pattern-search optimization method in order to obtain robustness to changes in the system parameters. The control system requires information about non-measurable state variables. For this purpose, it is proposed to use a multilayer observer. In order to show the advantages of the MLO system, this article also presents comparative studies with a classical observer. A number of simulation and experimental tests are carried out. The obtained results confirmed a much higher quality of control in the system cooperating with a multilayer observer compared to the system with a classical observer. Full article

Autonomous Vehicle Adoption in Developing Countries: Futurist Insights

by Nader Zali, Sara Amiri, Tan Yigitcanlar and Ali Soltani

Abstract

In recent years, research into autonomous vehicles (AVs) has become highly popular in industrialized nations due to their importance in the future success of smart cities. Research on this mobility technology and the critical elements affecting its development in developing countries, however, has been rather limited. This paper aims to shed light on the most influential elements of AV adoption in developing nations. A structural analysis approach is used, based on the primary qualitative data—that was gathered via an expert-opinion poll utilizing the fuzzy Delphi with a snowballing method and engaging 25 experts in the field in two rounds—, in accordance with the tradition of futurist research. The analysis has led to the identification of 11 key factors, from the initial factor pool of 54, affecting AV adoption in the case study context of Iran. The results of the analysis revealed the following conclusions, that fall under the policy and legislation domain, and present the most significant issues impacting AV adoption: (a) Future orientation of government—consistency and of accountability of policies, the long-term vision of the government for developing AVs industry; (b) Managing the international sanctions for foreign investment, and; (c) Funding mega projects to enable AVs. The results indicate that the establishment of legislation and the formulation of government policy regarding the provision of infrastructure, investment, and credit allocation are crucial for the development of AVs in Iran and other developing nations with comparable characteristics.
