In this paper the dynamics of the controlled pendulum is investigated assuming backlash and time delays. The upper equilibrium of the pendulum is stabilized by a piecewise constant control force which is the linear combination of the sampled values of the angle and the angular velocity of the pendulum. The control force is provided by a motor which drives one of the wheels of the cart through a...

In this study, a real-time control of the cart-pole inverted pendulum system was developed using fuzzy logic controller. Swing-up and stabilization of the inverted pendulum were implemented directly in fuzzy logic controller. The fuzzy logic controller designed in the Matlab-Simulink environment was embedded in a dSPACE DS1103 DSP controller board. Swing-up algorithm brings the pendulum near to...

We present a design for a low-cost, functional VLSI chip tester. It is based on the Apple Macintosh II personal computer. It tests chips that have up to 128 pins. All pin drivers of the tester are bidirectional; each pin is programmed independently as an input or an output. The tester can test both static and dynamic chips. Rudimentary speed testing is provided. Chips are tested by executing C ...

This paper proposes an approach for the minimum time swing upof a rotary inverted pendulum. Our rotary inverted pendulum is supported bya pivot arm. The pivot arm rotates in a horizontal plane by means of a servomotor. The opposite end of the arm is instrumented with a joint whose axisis along the radial direction of the motor. A pendulum is suspended at thejoint. The task is to design a contro...

Preliminary -The BERTScope BSX-series Bit Error Rate Tester introduces a receiver test platform capable of supporting emerging Gen4 standards and beyond. With the addition of powerful data processing and internal Tx equalization, the BERTScope supports protocol-based handshaking and synchronization with your device under test (DUT), including interactive link training at data rates up to 32 Gb/...

Key performance specifications Up to 1.6 Gb/s Pattern Generator/Error detector for fast, accurate characterization of digital communications signaling systems PRBS or 8 Mb user-defined patterns provide the versatility to debug or verify any combination of digital signaling ANSI jitter measurements (RJ, DJ, and TJ) to measure the impact of random and deterministic jitter on the total jitter at B...

Die Aufgaben, die ein Software-Tester zu erledigen hat, gehören bei vielen in der Softwareproduktion tätigen Personen zu den weniger attraktiven. Testen wird oft noch als notwendiges Übel am Ende der Softwareerstellung angesehen. Das Berufsbild des Testers ist nicht sehr angesehen und wird von den meisten nicht angestrebt. Diese Sichtweise steht allerdings im krassen Widerspruch zur Bedeutung d...

We present an adaptive tester for the unateness property of Boolean functions. Given a function f : {0, 1}n → {0, 1} the tester makes O(n log(n)/ε) adaptive queries to the function. The tester always accepts a unate function, and rejects with probability at least 0.9 if a function is ε-far from being unate.
