On the macro scale, feedback control is routinely applied to improve performance and enable new tasks in complex and uncertain systems operating in noisy environments. Our lab has focused on applying feedback control ideas to systems on the micro scale. Here we show how control methods can improve existing performance in the UCLA lab-on-a-chip electrowetting system and can create entirely new capabilities in our 'micro fluidic tweezers' cell steering devices.In the Electro-Wetting-On-Dielectric (EWOD) system developed at UCLA by CJ Kim, a grid ....etc

Real-time systems play a considerable role in our society, and they cover a spectrum from the very simple to the very complex. Examples of current real-time systems include the control of domestic appliances like washing machines and televisions, the control of automobile engines, telecommunication switching systems, military command and control systems, industrial process control, flight control systems, and space shuttle and aircraft avionics.

All of these involve gathering data from the environment, processing of gathered data ....etc

Abstract


Methods to synthesize controllers for nonlinear systems are developed by exploiting the fact that under mild differentiability conditions, systems of the form:

x = f (x) + G(x)u
can be represented in quasilinear form, viz:
x = A(x)x + B(x)u
Two classes of control methods are investigated:
¢ zero-look-ahead control, where the control input depends only on the current val¬ues of A(x), B{x). For this case the control input is computed by continuously solving a matrix Ricatti equation as the system progresses along ....etc

A practical method of modeling wind generator control systems for network simulation using Matlab-Simulink is presented. The interface developed between PSS/E and Matlab-Simulink allows the models generated to be used directly in PSS/E dynamic simulation. Fundamentally, modeling involves understanding the dynamics of equipments to be modeled and deriving the differential and algebraic equations which are coded using a high level computing language. For network elements resilient to change, the latter remains the method.
However, wind generator ....etc

In Part 1, the instructor introduces control systems in a PowerPoint presentation. Then students begin building robots and writing a simple computer program that will run the robot in a straight line. Next students test their robots. In Part 2, the instructor presents the second part of the PowerPoint and students use closed loop controls to run the robot on straight and curved lines. In Part 3, the instructor discusses control systemsâ„¢ involvement in nanomanufacturing. ....etc
