Application of AI in control systems (Intended research)
Dynamic systems modeling, structural properties, model reduction, identification, stability, feedback, optimality, robustness,adaptation, fault tolerance, and architecture have been among the central concerns on the theoretical side of ML and AI. These issues have been explored in a wide variety of settings: linear, nonlinear, stochastic, hybrid, distributed, supervisory, and others. The future is just as promising as there are a multitude of directions for future theoretical and applications research.
Some initial ideas for interesting research explorations are briefly outlined below:
Traditionally, control systems analysis and design has been based on detailed mathematical modelling of the processes and with fairly well-understood sources of uncertainty. However, a much larger opportunity arises in areas where such detailed, mechanistic mathematical models do not exist, and/or where the amount of uncertainty is significantly greater with unknown sources.
The key goal of neuroscience and cognitive science has been to build machines that can learn and think for themselves. Cybernetics was conceived as “the scientific study of control and communication in the animal and the machine”. Over time, this connection between control and cybernetics did not develop as fully as the mathematical control theory paradigm. New insights at the confluence of neuroscience, cognitive science, reinforcement learning, and AI to conceptualize new architectures for versatile, intelligent and adaptive controllers might be a good research initiative.
While there have been impressive advances in deep learning, many aspects remain only partially understood. For instance, there is considerable gap in understanding why deep neural networks have small generalization error in many real world applications. It is well-known fact that saddle points in high-dimensional non-convex optimization are a critical barrier in optimization and training of deep neural networks. There is thus an opportunity for systems and control theory community to contribute innovative non-convex optimization solutions to saddle point problem.)
