EE 308 New Mexico Tech Spring 2011 Lab 5 – Part 2 Final Project: Motor Speed Control Introduction and Objectives In this lab you will control the speed of a motor. Figure 1 shows the hardware setup‚ which is the same as for Week 1 of Lab 4. You will use the potentiometer on your evaluation board to set the desired speed of the motor‚ and you will control the speed through the PWM output of the HCS12. You will measure the speed of the motor using an input capture pin‚ and display the desired

It can be used in a class focused on management control‚ entrepreneurship‚ or management of small businesses. Al Fiorini‚ the manager of a small‚ but reasonably successful‚ mortgage lending company in Atlanta hired managers to run his business while he went back to school‚ for his executive MBA‚ in California.

Because of this current set-up‚ Mr Bevins believes that information regarding the divisions’ performance are not reported accurately and biased. .Mr. Bevins is interested if applying a control organization structure similar to Martex will resolve the conflict between the role of the corporate controllers and the divisional controllers.

Fred Bevin concern about the organizational status of his divisional controller. This concern occurred because Mr. Bevins foresaw increasing difficulties with the relationship between the corporate controller and the divisional controllers as the company introduced more modern control techniques. The existing relationship hampered him to could urge the development and use of new technique rapidly. His interest in the controller organization at the Martex Company led him to consider the adoption of

The set point of the flow control loop u M is manipulated by the level controller output. If the level h is too low the set point of the flow loop

From what we learned at Emerson Process Management last week‚ a transmitter is a tool which usually installed in the controller‚ which use to transfer the data from the field-site indicator to the control room‚ let say we use a Distributed Control System (DCS). Then‚ based from the data gathered an action might be needed to optimize the well performance‚ this is when the

And after the experiment‚ the students should be able to identify the parts of a feedback control loop‚ commission and operate an on/off controller and be familiar with Solenoid Valves and Motorized Control Valves. An on/off control is a type of feedback control where the control element is either at its fully-opened or fully-closed position. Figure 1 show the feedback control process where
