Stability Analysis of Distributed Engine Control Systems

Full Authority Digital Engine Control (FADEC), based on a centralized architecture framework, is being widely used for gas turbine engine control. However, current FADEC is not able to meet the increased burden imposed by the advanced intelligent propulsion system concepts. This has necessitated development of the Distributed Engine Control (DEC) system. FADEC based on Distributed Control Systems (DCS) offers modularity, improved control sys-tem prognostics, and fault tolerance, along with reducing the impact of hardware obsolescence.

Optimized Robust Adaptive Networks in Supervisory Control and Data Acquisition Systems

The Electric Power and Communica - tion Synchronizing Simulator (EPOCHS) system could provide great benefits to private industry and Department of Defense (DoD) power systems infrastructure by allowing simultaneous, synchronous simulation of communication and power system simulators to better understand the power grid under anomalous situations. Supervisory Control and Data Acquisition (SCADA) systems and the power grid infrastructure have recently been the focus of attention given the recent disclosure of potential cyber attacks. Applying Special Protection Schemes like the one used by the EPOCHS systems could provide a solution not only to cyber attack, but to possible cascading failures typical to power systems on current high-load demands. Utilizing an Internet-like architecture to implement such a backup and communication system is likely to be the most logical solution to providing a power grid intranet.

Evolvable Approaches to Software Verification and Validation

Research was conducted to integrate and advance current techniques in compilers, hardware architectures, and security to develop novel techniques to protect against physical attacks on encrypted embedded systems. The innovation in the approach was in exploiting the power of integrated software-hardware methods that do not require processor re-design. The hardware side of the innovation comes from using reconfigurable logic to implement security techniques in hardware. The reconfigurable logic in hardware, when combined with the ability of the compiler to instrument the code, can be used in powerful ways to strengthen the security of computing platforms. Several techniques were proposed and designed to address these objectives.

Color Touchscreen PLC

Unitronics (Quincy, MA) has added the V570-57-T20B to the company’s Vision570™ series of 5.7” Color Touchscreen PLCs. The model is lower in cost and has a white LED instead of fluorescent display backlight. The display of the V570-57-T20B is also TFT QVGA. Onboard I/Os can be added to this model by snapping a module onto the back of the PLC, and snap-in I/O Modules come in several configurations. I/O Expansion modules enable integrating up to 512 I/Os per Vision PLC.
