luenberger observer การใช้

• The celebrated Luenberger observer is named after him.
• More general state observers, such as the Luenberger observer for linear control systems, use a rigorous system model.
• The Luenberger observer for this discrete-time system is therefore asymptotically stable when the matrix A-LC has all the eigenvalues inside the unit circle.
• It is also important to take this positivity into account for state observer design, as standard observers ( for example Luenberger observers ) might give illogical negative values.
• As discussed for the linear case above, the peaking phenomenon present in Luenberger observers justifies the use of a signum ( i . e ., sgn ) of the estimated  measured output error.
