Neural Network control with stability and performance guarantees
Pre-conference workshop
This workshop deals with novel design methods allowing us to ensure closed-loop guarantees, such as stability and performance, in control approaches based on Neural Network (NN) policies. These guarantees are crucial as NNs become more and more integrated into control engineering, raising concerns about their reliability and predictability during and after training. The workshop first delves into innovative methodologies for designing NN controllers with stability guarantees through Linear Matrix Inequalities (LMI), highlighting the opportunities and challenges in their implementation. The second part of the workshop focuses on scalable methods and unconstrained optimization approaches for learning NN controllers that are guaranteed to maintain closed-loop properties during the training phase, with a focus on various kinds of closed-loop stability and distributed scenarios. The envisioned outcome of the workshop is for participants to gain insights into merging advanced machine learning techniques with traditional control systems. A final session and discussion will highlight open challenges and promising research directions in the field.

Module 1 - Matrix inequalities in NN control design
Module 1 comprises three sessions, the details of which are outlined below. It is structured to provide a unifying framework, based on matrix inequality tools, for the analysis of the stability properties of NNs and for the (possibly data-based) design of control systems which include NNs as a plant under control and/or the controller.
Module 2 - Unconstrained optimization approaches for stabilizing NN controllers
Module 2 comprises three sessions, the details of which are outlined below. It is structured to provide a comprehensive framework for designing neural network controllers with closed-loop stability guarantees through unconstrained learning. First, we introduce a parametrization encompassing all and only those control policies that stabilize a given time-varying nonlinear system. The main insight is that we can learn over stable operators to capture all stabilizing nonlinear control policies for a wide class of nonlinear systems.
Second, we present numerically efficient and unconstrained methods to approximate NN control policies that are stabilizing by design in both centralized and distributed frameworks.
