Intelligent device for the automatic parameterization through a digital twin of a

Summary of the technology

cyber-physical system CSIC and Universidad Politécnica de Madrid have developed an intelligent connectable device for the automatic parameterization of controllers of a physical and cybernetic system. This device has a new procedure designed to automatically parameterize the physical system controller. For this, it relies on a simulation in parallel and in real time of both the physical system model and the controller (digital twin).
Industrial partners are being sought to collaborate through a patent licence agreement.

Details of the Technology Offer

Digital twin for automatic parameterization.

Today's tracking and positioning systems require very precise controllers. Currently, there are limitations in the scope and optimal operation of controllers adjusted or tuned by manual and/or experimental parameterization, specifically due to the cross-correlation of the parameters and the cross-influence of the control parameters and the anticipatory components in the presence of hard nonlinearities like friction and backlash The proposed procedure is mainly composed of two steps: 1. Generation of digital twin of the cyber-physical system (physical system connected to the network). 2. Determination of the value of the optimal controller parameters To carry out the optimization process, three gradient-free heuristic methods are used: simulated annealing (SA), genetic algorithm (GA, Genetic Algorithm), and cross-entropy (CE, Cross-Entropy). The method of the present invention applies one of these heuristic optimization methods, in combination with the generated digital twin, to obtain the optimal value of the controller parameters that minimizes the chosen cost function.
