A Comparison of Analog and Direct Digital Control (DDC) of a Physical Process

The following report presents the development of a computer-based system designed to examine the response of a physical process is a process trainer, PT326, from Feedback Corporation. There are two main categories of control available to the user: (1) analog control and (2) digital control. Within each of these categories the following types of control systems are available: (1) Proportional control, (2) Proportional-Integral control, (3) Proportional-Integral-Derivative control and (4) On-Off control. The user can examine both regulator and servo response for any of the given control systems. All parameters associated with the selected control system are variable and user-input. The software is designed to be user-friendly. The user examines the response of the process to different control systems through the use of full-screen, high-resolution, color graphs. These graphs are linear and labeled. There are two main categories of graphs available to the user: (1) real-time monitoring and (2) graphs with labeled time base. Within each category there are four different graphs available. These graphs are available under any given control system. The user may also obtain hardcopy of these graphs.
