Control Co‐Design: An engineering game changer

Abstract

Over the last few decades, control engineers have focused on developing innovative control theories and algorithms to regulate systems. These control efforts are usually at the last stage of a sequential strategy that allows engineering departments to work independently and consecutively toward the design of new products and systems. Control algorithms are usually developed at the end of that sequential process, once the mechanical, electrical, and other subsystems are completely defined. This paper discusses a different approach, named Control Co-Design (CCD). Following a concurrent engineering strategy that considers multidisciplinary subsystem interactions from the beginning of the design process, CCD applies control concepts to design the entire system and reach optimal solutions that are not achievable otherwise. This approach is a game changer for the control engineer, who will be not only the designer of advanced control algorithms but also the natural leader of the design of new products and systems. This paper describes some historic engineering breakthroughs achieved by applying CCD and explores some relevant application areas. It also presents three complementary CCD methodologies that include control-inspired paradigms, formal mathematical co-optimization techniques, and co-simulation campaigns to enhance engineering creativity and achieve radically new optimal designs.

dymos: A Python package for optimal control of multidisciplinary systems

“…When dealing with the design of complex systems that include transient behavior, co-design becomes critical (Garcia-Sanz, 2019). Broadly there are two approaches: sequential co-design or coupled co-design (Fathy et al, 2001;Peters et al, 2009).…”

Wind farm flow control oriented to electricity markets and grid integration: Initial perspective analysis

“…The analysis has demonstrated that there exist frequency ranges where WFFC potentially interacts with WPPC, thus belying the popular belief that the electrical and power electronics control on the one hand, and the servo‐aeroelastic governance of wind turbines on the other, can be kept practically as decoupled in the control and system design process. The consideration of the existing dynamic interactions among components and subsystems would allow the application of the control codesign paradigm, either through option, cosimulation, or disruptive engineering solutions 115 . This integrated approach would therefore facilitate the removal of existing design barriers.…”
