  • Dependability and Functional Safety: Applications in Industrial Electronics Systems

    This article dealt with the topical subjects of the dependability and the functional safety of a system in light of the corpuses of dependability theory and functional safety standards. After some preliminary definitions on the notions of systems and service, the two corpuses were explicated. Concepts developed to give the matter an abstract but useful assessment were illustrated. The way issues treated by the two corpuses integrate with each other when dealing with a safety-critical system was also discussed. In the last section, the theoretical formulations were put into practice by focusing on the power inverter feeding the steering motor of an SbW system of a vehicle and on the ECU of the hoisting module of a passenger elevator.

  • Finite-State Machine Motion Controller: Servo Drives

    Digital controllers are used for modern power converter control and industrial automation. The functionality of the finite-state machine (FSM) provides an ideal platform for building a high-frequency field-programmable gate array (FPGA) controller for power electronics applications. This article develops the design of a current-control loop and the selection of switching logic for three-phase switching converters and ac electrical machines. The main design specifications are robustness to load and electrical parameters, fast dynamic response, reduced switching frequency, and simple hardware implementation. A discrete-event-type controller is proposed to meet previous specifications, designed as finite state automaton and implemented with an FPGA device. Furthermore, the actual controller architecture is based on the FPGA Spartan 3E. The experimental results are presented using a brushless ac (BLAC) motor as the converter load. However, this does not limit the wider applicability of the proposed controller, as it is suitable for different types of ac loads (rectifiers, inverters). View full abstract»

  • Three-Phase Current-Injection Rectifiers: Competitive Topologies for Power Factor Correction

    Three-phase current-injection rectifiers have been recently ranked among the most attractive AC-to-DC energy conversion topologies required in medium- and high-power applications. Their increasing popularity is mainly due to their structural and control simplicity and their high performance in terms of input power factor, current distortion, energy efficiency, and dc voltage regulation. They are actually considered solid competitors of six-switch rectifiers and the three-phase/switch/level (Vienna) topologies in applications where bidirectional power flow is not requested. The main benefit of the current-injection rectifier remains in the reduced number of high- frequency power semiconductors [two high- frequency insulated gate bipolar transistors (IGBTs) and three fast diodes, compared to six high-frequency IGBTs and six fast diodes for the six-switch rectifier, and three high-frequency IGBTs and 18 fast diodes for the three-phase/switch/level rectifier], making it more efficient and reliable.

  • From Traditional to Fractional PI Control: A Key for Generalization

    Proportional-integral (PI) controllers are the most common form of feedback used in industrial applications today [1][3]. The use of proportional and integral feedback also has a long history of practical applications [4]. For example, in the middle of the 18th century, centrifugal governors as the proportional feedback were applied to regulate the speed of windmills [5]. By the 19th century, it was known that using integral feedback could remove the offsets appearing in working with governors [6]. At present, PI control, still a very basic form of feedback, is also one of the first solutions often considered in the control of industrial systems [7]. On the other hand, in some applications, using the PI controller in its traditional form may not be satisfactory, and a more advanced controller is needed to achieve control objectives. In such cases, modified versions of the PI controller have been proposed to enhance the controller's performance. The fractional-order PI controller is one of these modified versions, and it is attracting increased interest in control system design uses [8], [9]. The idea of using such a controller originated with fractional calculus, known as a generalization for classical calculus [10]. The following section presents a brief review of recent fractional calculus applications in control system design. View full abstract»

  • The Age of Vacuum Tubes: Merging with Digital Computing [Historical]

    Wartime efforts aimed at developing superior technologies provided a major boost to vacuum tube development during and after World War II (WWII). The demand for tubes capable of generating microwaves for radar led to the development of the improved cavity-type magnetron in 1940 by John Randall (1905-1984) and Henry Boot (1917-1983) at the University of Birmingham, United Kingdom. This device was instrumental in ensuring the Allied Forces strategic superiority [1], [2]. After the war, such radar systems allowed far safer air and sea transportation and opened the way to new fields of scientific research. View full abstract»
