The development is illustrated using two physical examples: the control of a knife edge moving on a plane surface and the control of a wheel rolling without slipping on a plane surface. The physical significance of the theoretical results is described for these examples 展开 ...
Dynamics of controlled mechanical systems with material and program constraints— III. Illustrative examplesdoi:10.1016/0094-114X(89)90057-8The general theory and algorithms for solving the constrained system equations of motion presented in Part I and Part II are implemented for selected problems of ...
and controlled by aquantizedlaw, i.e., a piecewise constant time function taking a finite set of values. We show how to generate the control by, first, applyingmodel reductionto the original system, then using a “state-space bisection” method for synthesizing a control ...
awe shall not do more than give a few actual examples from Shanghai records 我们不会做更多比给出几实例从上海纪录 [translate] aIn the system dynamics methodology, a problem or a system (e.g., ecosystem, political system or mechanical system) is first represented as a causal loop diagram.[...
Examples of specific-topic tests are thePurdue Trade Tests, which include theTest for Electricians,Trade Information Test in Welding, andTrade Information Test in Engine Lathe Operation. Each one is a multiple-choice test of technical knowledge about tools and operations in a specific subject matt...

SUMMARY The question of a priori observability of a dynamic system, that is, whether the states of a system can be identified given a particular set of measured quantities is of utmost importance in multiple disciplines including biology, economics, and engineering. More often than not, some of...
In amaster clock system, electricity is used to give direct impulses to the pendulum, which in turn causes the clock’sgeartrain to move, or to lift aleverafter it hasimpartedan impulse to the pendulum. In various modern master clocks the pendulum operates a light countwheelthat turns throug...
rotating balance); an introduction to systems thinking, highlighting the fact that SDOF analysis is a building block for multi-degree-of-freedom (MDOF) and continuous system analyses via modal analysis; and a simple introduction to finite element analysis to connect continuous system and MDOF ...
