  • Power System Monitoring

    Power system monitoring is the most fundamental function of a system operator. Operators need to examine the prevailing system condition to establish whether the system is operating within acceptable thresholds. The decision system required for power system monitoring includes the infrastructure to measure signals such as voltages and reactive and active power flows, status of switches, and transferring them to the control center. The infrastructure used for measuring and transporting the information to the control is called Supervisory Control and Data Acquisition (SCADA) system while the decision support tool that filters and recreates the missing information is called State Estimation. SCADA performs the two main functions of data acquisition and supervisory control. Recently, there have been methods developed that not only identify if a system is observable or not, they can identify how much a single measurement observes different state variables and basically comes up with quantitative observability.

  • Rock Your World??-??Encouraging Process Perpetual Motion

    Every aspect of ensuring quality is an evolutionary process. In order to keep the overall process alive, one needs a little dynamic tension, something to keep the idea of continuous improvement moving forward. Methods to help the group cope with the evolution include the following: using diverse, cross- functional team members; executing continuous process improvements; and migrating activities into an automated tool. A crucial ingredient in process improvement is diversification. One can help encourage active engagement in collaborative process improvement (CPI) by publishing process helpers on the local intranet. The success of any innovation involves early adopters, the majority, and laggards. The rate at which employees adopt any change can be adjusted in several key ways. Each can raise or lower the stickiness of the change through the following variables: relative advantage, compatibility, complexity, trialability and observability.

  • StateSpace Models

    This chapter introduces state-space models for describing system dynamics. State-space models provide a scalable approach to modeling MIMO systems - those with multiple inputs and outputs. We define for state-space models many of the familiar concepts from transfer function modeling, such as poles and transfer functions. Further, it is shown how many of the techniques and results covered in earlier chapters can apply to state-space models as well, such as stability and dominant pole analysis. The concepts of controllability and observability, which are unique to state-space models are presented.

  • Modularity in Functional-Logic Programming

    Constructor-Based Conditional Rewriting Logic is a general framework for integrating first-order functional and logic programming that has been investigated in [9] giving an algebraic semantics for programs. In this paper, we introduce an immediate consequence operator TR for each program R and a fixpoint semantics that coincides with the algebraic one. We also propose an extension of the formalism with constructs for modularization, that lets us express hiding, export/import and inheritance. The fixpoint semantics does not characterize these constructs well and hence we propose two alternative semantics for programs: the operator TR itself, and the set of all term models (TR-fixpoints). The former is compositional and the latter is compositional and fully abstract w.r.t. a natural notion of observability.

  • ARCHGEN: Automated Synthesis of Analog Systems

    High-level design of analog systems is an open area that needs to be addressed with the emerging trend of integrating mixed analog-digital systems. Design methods compatible across the analog-digital boundaries would expedite the design process, and in this paper we address analog high-level design issues. An approach for systems-level synthesis of a class of analog systems is presented. A behavioral level for the analog domain is characterized in terms of state equations and transfer functions in the continuous and discrete domains. State-space representations are generated from transfer function specifications that exhibit system level characteristics such as controllability and observability as well as decoupled and parallel architectures. These state-space representations are synthesized into behavioral-level, technology-independent architectures composed of analog functional components. An intermediate architecture in a circuit implementation technology is synthesized from the behavioral architecture. The various algorithmic procedures for synthesis are implemented in the program ARCHGEN. Behavioral simulation is used for architecture verification and design space exploration.

  • Mathematical Description of Linear Dynamical SystemsReceived by the editurs July 7, 1962 and in revised form December 9, 1962.

    There are two different ways of describing dyasmicel systems: (i) by means of state variables and (ii) by input/output relations. The first method may be regarded as an axiomatization of Newton's laws of mechanics and is taken to be the basic definition of a system. It is then shown (in the linear case) that the input/output relations determine only one part of a system, that which is completely observable and completely eontrollable. Using the theory of controllability and observability, methods are given for calculating irreducible realizations of a given impulse-response matrix. In particular, an explicit procedure is given to determine the minimal number of state variables necessary to realize a given transfer-function matrix. Difficulties arising from the use or reducible realizations are dlaeussed briefly.
