Conference paper (peer-reviewed)abstract
- We present a strategy for failure resilient cloud control using model predictive control (MPC) extended with explicit recovery. Based on an arbitrary and unmodified device controller, the remotely operated MPC can safely manipulate the network controlled plant through temporary adjustment of an error signal generator. We show ways to implement the reliable cloud controller, relate it to two-degrees-of-freedom control and robust MPC, and determine stability. Simulations illustrate the obtained performance and resilience to failure. In the conclusion, we elaborate on these results and the concept of elastic control.
