The motor is a permanent magnet that isstationary and ideally proportional to the applied voltage when there is no load applied. Thetachnogenerator is a small permanent magnet machine which rotates to produce a back EMFproportional to speed, which is used to indicate the rotation speed. The tachnogenerator providesa signal representing speed, independent of the motor loading. The responses of the motor to thevaried inputs are not immediately observed which can be recognized as the time constant. Bothsystems can be used to analyze the stability of

described above allows for the experimental characterization of the dynamic behaviorof important MEMS structures under vastly different environments, but in order to fully model theirbehavior another important preliminary experiment must be conducted. In order to properly modelthe dynamic behavior of MEMS, their mechanical material properties must be known. The twomain properties that must be determined are the elastic modulus and the structural damping. Thenatural frequencies of the microcantilever beams are also needed, but this information is used so thatthe material properties can be determined. Many references are available for the elastic modulus ofpoly-Si 12-14, but structural damping properties are not well characterized. Therefore, the

on the DSP towards an H-bridge power converter to drive the motor. The material presented in this study is an effort to develop hands-on activities for students toimplement control system compensators, and not only the basic required components but alsoseveral alternatives to accomplish such task are presented. There have been multiple effortselsewhere to create prototype systems to implement control systems, in particular PIDcontrollers. For example, Murphee et al.1 controlled the position of a block attached to a screwnut that travels along a ball screw by implementing a PID controller on a DSP to create ademonstrative setup of control system concepts for undergraduate mechanical engineeringstudents. A LabVIEW program was developed to
performance standards. Usage of fossil fuels for operations is expensive. In order to minimize energy consumption it is better to rely on efficient and passive design measures. • Scarcity of fresh water is the basic problem in many parts of the world. A sustainable building seeks to reduce, control site runoff, use water efficiently, and recycle water for on-site use when feasible. • Environmentally preferred products are used to minimize life-cycle environmental impacts such as global warming, resource depletion, and human toxicity.
