Introduction. Week 1- Fall 2009. Dr. Kimberly E. Newman. University of Colorado. General Introduction. The scope of embedded system design platform has expanded from the traditional system of a programmed microprocessor or microcontroller to the use of “embedded cores and processors”, and reconfigurable devices as components of a digital system.  This growth in technology provides greater design flexibility, in that the system architect/designer can choose the mix of hardware and software components of a system, and have more control over the computing architecture and organization of the system.

PID “Actions”. The PID controller has three . actions. . Each of these has its own purpose:. P-Action is infinitely sensible. The command out to the actuator is proportional to the size of the error. If the error is small, the action is a nudge. If the error is big, the action commanded is large.. 2. Learning Objectives. Upon completion of this content, the learner will be able to.
