Computer vision : a modern approach = 计算机视觉 : 一种现代的方法

A tutorial account of variable structure control with sliding mode is presented. The purpose is to introduce in a concise manner the fundamental theory, main results, and practical applications of this powerful control system design approach. This approach is particularly attractive for the control of nonlinear systems. Prominent characteristics such as invariance, robustness, order reduction, and control chattering are discussed in detail. Methods for coping with chattering are presented. Both linear and nonlinear systems are considered. Future research areas are suggested and an extensive list of references is included. >

Variable structure control: a survey

Active filtering of electric power has now become a mature technology for harmonic and reactive power compensation in two-wire (single phase), three-wire (three phase without neutral), and four-wire (three phase with neutral) AC power networks with nonlinear loads. This paper presents a comprehensive review of active filter (AF) configurations, control strategies, selection of components, other related economic and technical considerations, and their selection for specific applications. It is aimed at providing a broad perspective on the status of AF technology to researchers and application engineers dealing with power quality issues. A list of more than 200 research publications on the subject is also appended for a quick reference.

The aim of this paper is to present a review of current control techniques for three-phase voltage-source pulsewidth modulated converters. Various techniques, different in concept, have been described in two main groups: linear and nonlinear. The first includes proportional integral (stationary and synchronous) and state feedback controllers, and predictive techniques with constant switching frequency. The second comprises bang-bang (hysteresis, delta modulation) controllers and predictive controllers with on-line optimization. New trends in current control-neural networks and fuzzy-logic-based controllers-are discussed, as well. Selected oscillograms accompany the presentation in order to illustrate properties of the described controller groups.

Current control techniques for three-phase voltage-source PWM converters: a survey

The 20th century has been characterized by the great strides that have been made in science and technology. In the first half, the developments were mainly hardware dominated. During this period, the mechanical complexity, precision and speed of production machinery in industrial installations increased considerably. This period can therefore be dubbed as the hardware age. In a similar manner, the second half of the century can be referred to as the software age, since the dominating power during this period was software. At the beginning, electronics, which was until then confined to communications area, penetrated industrial installations and the level of automation increased considerably in the form of “hard automation”. The development of microprocessors in 1970’s provided a new impetus to industrial evolution. It became possible and economically feasible to realize many complex functions in a simple manner, by the use of appropriate software. At later stages, a synergetic fusion of different technologies, especially of mechanical and electronics technologies and computer science took place and, as a result, hard automation left its place to flexible automation, culminating in computer controlled processes, which possess a certain degree of intelligence and autonomy. The age of mechatronics (mechatronics age) was thus born. Factories incorporating such technologies are no longer“factories of the future” but “factories with a future”.

Squirrel Cage Induction Motor Control System in the Sliding Mode

This paper presents a sensorless torque estimation algorithm for multidegree-of-freedom flexible systems. The proposed algorithm makes it possible to estimate externally applied torques due to flexible system's interaction with the environment without taking any measurement from the system. The algorithm is based on modifying the disturbance observer in order to decouple the reflected torque waves out of the total disturbance on the actuator. Then Reflected torque waves are used along with the actuator's current and velocity to estimate flexible system parameters, dynamics and the external torques or disturbances. Several experimental results are included in order to confirm the validity of the proposed torque estimation algorithm.

Sensorless torque estimation in multidegree-of-freedom flexible systems

Motion control technologies are introduced in a huge number of products: electric vehicles, robots, mass storage areas, machine tools, etc. Many new products have developed based on previous studies on motion control. Recent achievements in motion control have indicated that innovation in this area is accelerating. For example, many companies have put robots with force sensing to practical use in the past few years. They have a wide variety of applications such as deburring, polishing, and assembling. Further development of haptics is strongly required for telesurgery, rehabilitation, and nursing care support. The development of high-accuracy positioning/tracking control has shortened the access time of mass storage areas. Sophisticated integration of actuators and sensors technologies has created many innovative techniques for new motion control systems. It is quite obvious that motion control is becoming more and more important as one of the key technologies in industrial electronics. Therefore, this "Special Section on New Emerging Technologies in Motion Control Systems - Part I" aims at presenting to the industrial electronics audiences the most advanced and relevant results in the field of motion control. The Guest Editors summarize the 14 articles from, various areas, that comprise the special section.

Introduction to the special section on new emerging technologies in motion control systems - Part I

In shared human-robot environments, control systems operate based on the information about both human and robot activities to facilitate the successful collaboration between the two. This paper contributes to the emerging field of human-robot collaboration (HRC) by unifying human action recognition (HAR) and high-level robot control technique into single control system. Approach in this paper includes artificial neural network based classifier for recognition of human activity and task-based control as an example of high-level control technique. Classifier is developed based on the data from wearable sensors attached on the human arms. Recognized human activity is used as the input for the selection of functions that describe robot's activity (task). This papers combines both the theoretical approach to the task-based control and it's synergy with HAR while the developed artificial neural network classifier is experimentally validated.
