The delays are stochastically determined by the last few delays. The proposed optimal controller can be efficiently computed by iteratively solving a Riccati difference equation, provided that a discrete-time Markov jump system equivalent to the sampled-data system is stochastic stabilizable and detectable. Sufficient conditions for these notions are provided in the form of linear matrix inequalities, from which stabilizing controllers and state observers can be constructed.

Research paper thumbnail of Stable robust controller inspired by the mammalian limbic system for a class of nonlinear systems

2020 American Control Conference (ACC), 2020

These architectures are promising in terms of their learning ability and low computational cost. However, the lack of rigorous stability analysis and mathematical proofs of stability and performance has limited the proliferation of these controllers. To address this drawback, this paper proposes a modified brain emotional neural network structure using a radial basis function inside the Thalamus and an emotional signal based on an integral action structure to increase performance. Mathematical stability proofs are provided, together with numerical simulations, demonstrating the superior performance obtained with the new modifications proposed to the emoional learning-inspired control.
