    This paper presents a one-dimensional position measurement for a suspended object in a large-gap magnetic suspension system which allows wider range of control. The position measurement system uses a linear photosensor array to detect the position of the suspended object. The proposed measurement is simple, effective, and less expensive than other methods in large-gap magnetic suspension systems View full abstract»

    Electronic ballasts must provide enough open circuit voltage to start the fluorescent lamp and current limiting while the lamp is running. Resonant inverters may be utilized in electronic ballasts because of their load-dependent characteristics. The three basic types of resonant inverters, the series-loaded, parallel-loaded, and the series-parallel-loaded, are compared using fundamental approximat... View full abstract»

    Real time detection methods of moving vehicles and pedestrians for navigation of the mobile robot are proposed. The method is based on a locomotion strategy, viz. signature-based stereotype motion. Signature of the moving vehicle is the shadow underneath the vehicle which is darker than any other parts of the asphalt paved road. Signature of the pedestrian is rhythm of walking. Rhythm of walking i... View full abstract»

    A new modeling approach for the spectral analysis of pulsewidth modulated (PWM) converters with independent inputs is developed. The key of this approach is to extend the Volterra functional series to nonlinear systems with multiple independent inputs. After formulating the state-space equations describing the dynamical behavior of PWM converters, the Volterra transfer function characterizing the ... View full abstract»

    Improved reliability and fault tolerant operation of power converter systems are extremely important for industrial AC drives. The paper considers variable frequency variable voltage operation of a three-phase induction motor in single-phase mode for two common faults of a three-phase inverter, i.e., open base drive and device short-circuit. The motor performance has been extensively analyzed in s... View full abstract»

    Two levels of an innovative adaptive switching pattern (ASP) for use in the control of induction machines are described. The ASP is based on a tolerance band control strategy resulting in nearly sinusoidal stator currents. The first level (ASP1) significantly increases the switching time thereby eliminating the very fast switching sometimes experienced. The second level (ASP2) reduces the number o...

    A method allowing a mobile robot to measure accurately its distance from external objects is introduced. It only requires a single uncalibrated camera and a dynamic vision system. The method was evaluated in an optical laboratory and also in outdoor-experiments. Even in outdoor-experiments with a vehicle moving at a speed of 30 km/h, errors of less than 1% of the true distance were achieved in rea... View full abstract»
