IPC: G05B13/02
Filed: 2000-10-24
Abstract: PROBLEM TO BE SOLVED: To obtain high-speed real-time identification and estimation for time constant and varying systems. SOLUTION: An estimation criterion for H∞ is determined newly, and a high-speed algorithm for a deformed H∞ filter is developed based on this criterion, while a method for high-speed time-varying system identification is proposed, based on this high speed H∞ filtering algorithm.

It matches perfectly with the high-speed Kalman filtering algorithm at the limit of the upper limit value. If the estimated value of an impulse response is obtained, a pseudo-echo can be determined successively based on the value. Subtracting the pseudo-echo from the real echo and canceling echo can provide an echo canceller.
