The paper proposes a new estimating algorithm for linear parameter varying systems with slowly time-varying parameters when the rate of change of individual parameters is different. It introduces a true probability density function, describing ideally the behaviour of parameters. However, as it is unknown, we search for its best approximation. A convex combination of point estimates, defined by individual hypotheses about the true probability density function, is then approximated by a single density. That serves as the best available description of parameters' behaviour and it is therefore suitable e.g. for prediction purposes.
Článek představuje nový rozhodovací algoritmus pro lineární parametry různých systémů s pomalými časově-variačními parametry, kde je velmi malá pravděpodobnost, že se jednotlivé parametry změní.
