A conventional approach involves a pulse-width-modulated converter which is interfaced to the utility voltage (for example at the 13.8 kV level) through a line-frequency transformer. This increases the size and the cost of the system and introduces additional losses. This paper describes a per-phase, all-active approach where the need for a line-frequency transformer is eliminated by series connected converters. This all-active solution is a hybrid combination of two (or more) converters switching at line frequency (or its low multiple) and one converter pulse width modulated at a higher switching frequency. This paper includes the following: criteria for optimization, experimental results from a proof-of-concept laboratory prototype for an active filter application, and a comparative evaluation with the six-switch PWM converter for an SVC application.","PeriodicalId":404447,"journal":{"name":"Proceedings of the IECON'97 23rd International Conference on Industrial Electronics, Control, and Instrumentation (Cat.

One is called the target AMR and the other one is the tracker AMR. At first, the authors introduce the structures of these AMRs, where the sensor arrangements are examined. A fuzzy logic controller is designed to implement the path planning (wall following) for the target AMR such that the target can go straight or move in a circle. They design two controllers, a steering angle controller and speed controller, for the tracker AMR such that the tracker AMR can track and follow the target AMR. Finally, the online fuzzy steering angle and speed controllers are developed such that the tracker AMR can track the target AMR and go with a fixed distance after the target. Both simulations and real-time manipulations demonstrate the feasibility and effectiveness of the proposed schemes.","PeriodicalId":404447,"journal":{"name":"Proceedings of the IECON'97 23rd International Conference on Industrial Electronics, Control, and Instrumentation (Cat.

However, the SRM has the disadvantages of high current harmonics and low power factor because of the pulse-type discontinuous excitation. This paper investigates an SRM drive system with reduced harmonics and improved power factor. The system consists of a switching power converter with power factor correction (SPC-PFC), a DC/DC power converter and a three-phase inverter. The SPC-PFC is designed to produce a pure sinusoidal input current, improve the power factor and reduce harmonics. The performances in the proposed system are verified through both simulation and experiments.","PeriodicalId":404447,"journal":{"name":"Proceedings of the IECON'97 23rd International Conference on Industrial Electronics, Control, and Instrumentation (Cat.

Obstacles in the work space could be stationary or moving objects. The collision-free motion of the robot is generated in the robot's configuration space. Based on the fact that the static obstacles always impose constraints on the motion of the robot while the time-varying obstacles only impose constraints on the motion of the robot within the specific time period, hence the time-varying obstacles are treated differently from the static obstacles. The motion planner is composed of two components, i.e. a static planner and a dynamic planner. The potential field mechanism used for the motion planner will guarantee its completeness. Simulation results demonstrate the performance of the planner for a planar robot.","PeriodicalId":404447,"journal":{"name":"Proceedings of the IECON'97 23rd International Conference on Industrial Electronics, Control, and Instrumentation (Cat.

Starting from the description of an induction motor by the help of the space vectors, three basic control strategies are discussed. First, the most popular field oriented control (FOC) is described. Secondly, the direct torque and flux vector control (DTFC) method, which-in contrast to FOC-departs from idea of coordinate transformation and analogy with the DC motor, is briefly characterized. The last group is based on feedback linearization control (FLC) and can be easy combined with sliding mode control. The simulation and experimental oscillograms that illustrate the performance of the discussed control strategies are shown.","PeriodicalId":404447,"journal":{"name":"Proceedings of the IECON'97 23rd International Conference on Industrial Electronics, Control, and Instrumentation (Cat.

Many of these clocks contain insufficient capacitor ride-through capability or ineffective battery backup. Therefore, these devices are very sensitive to short duration power interruptions. These interruptions manifest themselves by causing the clock display to blink, which in turn causes the customer's perception of the power quality of the utility to be negative. Described in this paper is a UPS which employs double-layer capacitors for the backup power supply. The UPS design is based on a push-pull amplifier that utilizes a simple oscillator circuit to produce the 60 Hz AC voltage needed for the load. The UPS has been constructed and extensively tested in the laboratory on a digital alarm clock. Backup power can provided to the clock for over 30 seconds using a double-layer capacitor bank, which is sufficient since most power interruptions are cleared within 30 seconds.","PeriodicalId":404447,"journal":{"name":"Proceedings of the IECON'97 23rd International Conference on Industrial Electronics, Control, and Instrumentation (Cat.

Compared to other modern complex control algorithms, the observer algorithm is very simple and effective in reducing the effect of the disturbances. An IP speed controller using ITAE is used as the main controller, and the parameter controller (PC) is used to make the system robust with respect to rotor inertia negative variations; the PC is a parameter controller which selects a moment of inertia J according to the load torque to control the system response. Also, to overcome practical difficulties in obtaining inertia variation for the experiments, an electrical equivalent circuit was proposed and used.
