May 31, 2013: 169 North American universities are coming together to realize a common goal that they all share – to develop a first-rate educational program for electric energy systems. With the help of funding from various organizations including NSF, ONR (Office of Naval Research), NASA and EPRI, the universities have established a consortium to collectively evolve and promote a curriculum for sustainable power.

How the dSPACE DS1104 R&D Controller Board and CP 1104 I/O Board Are Being Used in the Electric Drives Lab
The CP1104 I/O board is an input-output interface board between the
Power Electronics Drive Board and DS1104 controller board. The CP1104 I/O board helps monitor the inputs (i.e. motor current, speed, voltage, etc.) in each discrete-time step. Based on the inputs and the variables that need to be controlled (i.e. motor speed or torque), the DS1104 R&D board takes the programmed action to generate the controlled digital signals. This type of action is governed by what is programmed in the board with the help of a MATLAB®/Simulink® real-time interface.
With the use of ControlDesk® by dSPACE, students can monitor all inputs to the CP1104 I/O board in real time and control any variables from the MATLAB/Simulink model (i.e. speed, torque, voltage).
The DS1104 board provides a quick implementation time and ease of use, enabling students to focus on the basic concepts of electric machines and drives. An example setup is shown above.
