Co-Design of Multimodal CPS Architectures and Adaptive Controllers

Abstract:

The project is an on‐going collaborative effort between Massachusetts Institute of Technology and University of Pennsylvania since 2011. The ultimate goal of the project is to develop techniques for the co‐design of multi‐modal distributed embedded architectures and adaptive controllers so as to (1) achieve a high quality of control (QoC) in a physical application where multiple physical plants have to be simultaneously controlled in real‐time; (2) guarantee a given quality of service (QoS) requirement of other coexisting real‐time, non‐control applications; and (3) optimize the architectural resource use. Our specific objectives are (i) the development of analysis tools for a multi‐modal architecture with verifiable implementation that can guarantee specified QoC and specified QoS requirements subjected to given architectural resource constraints, (ii) the development of synthesis tools for the multi‐modal architecture consisting of co‐designed modes and mode‐transitions together with control strategies, and (iii) validate the multi‐modal co‐design architecture in a practical setting. To date, we have developed techniques to construct switching controllers that ensure stability of a control system subject to uncertain propagation delays between system components, subject to an assumption about the maximum number of delayed messages within any window of a given size. To establish a co‐design framework, we complement these control design techniques with platform analysis and configuration techniques that provide guarantees that the assumption about message delays is satisfied. A case study from the automotive domain demonstrates that the co‐design approach enables more efficient use of platform resources compared to a conventional design.
