Minimax Performance Limits for Multiple-Model Estimation

Kjellqvist, Olle LU orcid (2024) p.2540-2546
Abstract
This article concerns the performance limits of strictly causal state estimation for linear systems with fixed, but uncertain, parameters belonging to a finite set. In particular, we provide upper and lower bounds on the smallest achievable gain from disturbances to the point-wise estimation error. The bounds rely on forward and backward Riccati recursions-one forward recursion for each feasible model and one backward recursion for each pair of feasible models. We give simple examples where the lower and upper bounds are tight.
Abstract (Swedish)
Artikeln behandlar fundamentala prestandabegränsningar för strikt kausala tillståndsskattningar hos linjära system som beskrivs av ett ändligt antal modeller. Systemet antas beskrivas korrekt av en av modellerna, men det är okänt vilken av kandidaterna som är korrekt. Vi ger metoder för att beräkna övre- och undre begränsningar på minimax prestanda, defininerad som förstärkningen från störningar till punktvis skattningsfel. Begränsningarna beräknas genom Riccatirecursioner som går framåt och bakåt i tiden.
