CEAC Computer Controlled Controller Tuning Unit

The Computer Controlled Controller Tuning Unit, "CEAC", provides the tools to simulate different industrial processes in a HIL system and control them with a commercial industrial controller. The CEAC unit works in conjunction with a computer, in order to visualize all signals involved in the process and adjust the parameters of the industrial controller.The CEAC unit is provided with a set of practical exercises, through which the students will familiarize with the control of most common type of industrial processes, and how to control them with a commercial industrial controller with the following controls: PID (proportional integrative derivative) pPI (predictive proportional integrative), gain scheduling PID for non-linear systems, etc.

The CEAC unit is an advanced system that operates in conjunction with a computer, which allows to change the control parameters performed by the industrial controller.Through the CEAC unit the students will understand the operation mode of an industrial controller. They will learn how to set up thecontroller to control different systems, such as 1st and 2nd order system, time-delayed system, systems with non-linear actuators, etc. andhow to control them using different types of controls such as PID, pPI, gain scheduling, etc. The CEAC unit main components are: the industrial controller and the System Simulator. Both components have an USB connector tocommunicate easily with the computer.In the following lines there is a brief description of each block:

• Industrial Controller: the controller uses one analog input and one analog output, that is enough to perform the control of the singleinput-single output (SISO) systems.The analog input is used to connect the process variable signal (PV). The analog output is used for the output controller signal (O/P).Once the control is configured, the control parameters can be change through the software.
• Process Simulator: performs a real-time hardware-in-the-loop (HIL) simulation of different industrial process, in order to controleach one with the industrial controller. The process simulator can be configured, with the type of the process to simulate (integratorsystem, first order system, second order system, etc.) and the parameters of the system. The simulated system takes the O/P signal fromthe industrial controller and provides the feedback of the system (PV) to the controller.

This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + ControlInterface Box + Computer Control, Data Acquisition and Data Management Software Packages, for controlling the process and allparameters involved in the process.
