Feedback Based Performance Management and Fault Tolerance for Networked and Embedded Computing Systems

In the second part of this dissertation, we further exploit the use of feedback control to achieve fault tolerance for real-time embedded control systems. We propose ORTGA (On-demand Real-Time GuArd), a new fault tolerance architecture which utilizes feedback control based software execution. ORTGA delivers the same functionalities as previously proposed Simplex architecture, with the same high fault coverage and reliability but with much more efficient resource utilization and flexibility. Hence it can be deployed in a wide range of real-time embedded applications to provide fault tolerance. We implemented ORTGA in an inverted pendulum testbed to demonstrate its efficacy and efficiency. Based on the ORTGA design, we discussed the fault tolerance and scheduling co-design problem and its solutions.
