  • CDC - Analysis and use of several generalized ℋ(∞ mixed sensitivity frameworks for stable multivariable plants subject to simultaneous output and Input Loop breaking specifications
    2015 54th IEEE Conference on Decision and Control (CDC), 2015
    Co-Authors: Karan Puttannaiah, Justin A. Echols, Kaustav Mondal, Armando A. Rodriguez
    Abstract:

    In this paper, we present and examine three generalized mixed-sensitivity control design frameworks for linear time invariant (LTI) plants for trading off properties at distinct multivariable Loop-breaking points, while being able to handle a broad class of closed Loop (e.g. ℋ(∞, ℋ2, frequency- and time domain) specifications. Multiobjective tradeoff paradigms are developed and analysed for ill-conditioned plants having large relative gain array entries - plants that have received considerable attention in the literature without yielding a direct systematic design methodology. We provide insight into the effectiveness of each approach and discuss the trading-off of properties at distinct Loop-breaking points. This is done by exploiting the Youla-Jabr-Bongiorno-Kucera-Zames (YJBKZ) parameterization, the resulting convexification, and efficient state-of-the-art convex solvers that can be applied to smooth as well as non-differentiable problems. Moreover, we also show how our approach can be applied to multivariable infinite-dimensional plants. Specifically, by using finite dimensional approximants that converge in the uniform topology, we obtain near-optimal finite dimensional controllers for the infinite dimensional plant. Illustrative examples are provided for a thermal PDE and a retarded time delay system.

    Abstract:

    In this paper, we present a generalized mixed-sensitivity multivariable framework for linear time invariant (LTI) plants that can handle a broad class of closed Loop (e.g. ℋ∞, ℋ2, frequency- and time domain) objectives while being able to directly and systematically address the problem of trading off properties at distinct Loop breaking points. This is done by exploiting the Youla-Jabr-Bongiorno-Kucera-Zames (YJBKZ) parameterization, the resulting convexification, and efficient convex solvers that can be applied to smooth as well as non-differentiable problems. Our approach is shown to be particularly useful for ill-conditioned plant having large relative gain array entries - plants that have received considerable attention in the literature without yielding a direct systematic design methodology. Moreover, we also show how our approach can be applied to multivariable infinite-dimensional plants. We specifically show that by suitably approximating the infinite-dimensional plant with a finite-dimensional approximant, a near-optimal finite-dimensional controller can be designed for the infinite-dimensional plant. Illustrative examples are provided.

  • A Wide-Range Charge Controller for Solar Sensor
    Journal of Circuits Systems and Computers, 2015
    Co-Authors: Cihun-siyong Alex Gong, Long-xi Chang
    Abstract:

    The solar energy conversion driven by the solar sensor (or the so-called solar cell) has become an important and feasible way to solve global energy crisis while at the same time minimizing environmental pollution. The solar charge controller is the key of its active system for the signal processing circuits involved. In this paper, a fully integrated solar charge controller is presented. The charger has wide Input voltage range about 10–28 V for the solar-powered panel. The Input Loop regulation is used here as the maximum power point tracking protection. This charger also provides different kinds of battery voltages about 4–12 V. The controller system uses just one error amplifier (EA) and no external compensation components is needed. Besides, this controller has 600-kHz pulse-width modulation (PWM) and offers the over-current/over-voltage protection. Other components like bandgap, reference generator, saw-tooth generator, register controller and driver circuits are all implemented in this circuit. This chip is fabricated in a 0.4-μm 5 V/40 V 2P4M process. The power consumption of this full-integrated solar charge controller IC is about 10 mA.
