A microprocessor-based multivariable controller incorporating state feedback as well as feedforward control for fast regulation and stability of a current source inverter-fed induction motor (CSI-IM) drive is presented. The design of the state feedback controller is based on the industrial regulator theory together with the pole-placement technique applied on a linearized d-q axes state-space model of the drive and includes a reduced-order observer to estimate the inaccessible states such as d-q axes rotor currents. A feedforward control in terms of reference and disturbance inputs has been added to the feedback controller-observer to obtain faster dynamic response. The controller is implemented in real-time using an Intel 8085 microprocessor kit. The hardware and software aspects of the controller are discussed, and test results are presented and compared with digital simulation results for step changes in references and load torque. Typical results show the possible improvement in response with the addition of feedforward control.<>

A software tool which presents analytical solutions of Laplace's equation offers several advantages over numerical techniques, such as the opportunity to study parametric dependence of the solutions and the ability to deal easily with derivatives and highly curved surfaces. The principal obstacles are overcome by a computer program which guides the user through a series of graphical menus to the correct problem statement. The solution is then furnished in a text editing window, and can be copied and exported to other programs, such as word processors and spreadsheets.<>

In 1981 a mining equipment manufacturer approached the Mine Safety and Health Administration with a combination fuse contactor device requesting that it be permitted as a means of protection for low and medium voltage, three phase AC trailing cables. The concept behind the design of the vacuum contactor-fuse device was to use a vacuum contactor to provide protection to a specific current level during abnormal circuit conditions. If fault currents exceeded this level, a current limiting fuse would be used to interrupt the current before the vacuum contractor could open. The authors describe the tests and criteria developed to ensure that the device provided no less protection than a molded case circuit breaker. Details of the laboratory tests are presented. The vacuum circuit breaker meets 30 CFR 75900, 75902 and 75601 in that it provides suitable protection against undervoltage, grounded phase, overcurrent, and short circuits.<>

A concept of an electromagnetic structure which exploits the excellent characteristics of a rare-earth magnet is proposed. Thin rare-earth metal magnet pieces are mounted on the surface of the stator teeth which face the airgap. The rotor is an inductor type. This type of motor is suitable for low-speed, high-torque applications by the action of inductor teeth. The relationship between the performance and electromagnetic geometry is investigated through the finite element method (FEM) analysis and experiments. The principle of torque generation and the associated characteristics are introduced.<>

A framework is formulated for the design and development of a user friendly CAE (computer aided engineering) package for drive system dynamics. The authors describe the design principles and algorithms of such a modular CAE package and its implementation on a personal computer. An effort has been made to fill the need for an interactive simulation to assess the torque ripple, losses, efficiency, torque and speed responses, and their bandwidth, as well as the suitability of the drive system for a specific application. One such CAE package, PMBD, has been developed, and key results using the package are presented to highlight the implemented features. Various user friendly features and dynamic and steady-state analysis results are described in detail.<>

A DC-side commutated zero voltage switching (ZVS) PWM 3- Phi VSI topology is discussed. This topology consists of a typical six-switch bridge with the addition of a simple DC bus commutating subcircuit which can provide, on demand, the necessary for soft switching zero-volt interval across the inverter DC bus. The objective of this work is to identify a specific PWM technique which, in combination with the proposed ZVS scheme, can provide optimum overall converter switching performance. Moreover, the combination of the inverter topology and the modulation strategy proposed yields a soft switching environment at the lowest possible switching frequency.<>
