On the H∞ Fixed-lag Smoothing: How to Exploit the Information Preview
نویسنده
چکیده
The problem of the continuous-time H∞ fixed-lag smoothing over the infinite horizon is studied. The first solution to the problem is derived in terms of one algebraic Riccati equation of the same dimension as in the filtering case and the mechanism by which the performance improvements with respect to the H∞ filtering occur is clarified. It is shown that the H∞ smoother exploits the information preview in an “H manner.”

H∞ control and estimation with preview-part II: fixed-size ARE solutions in discrete time
H∞ preview control and fixed-lag smoothing problems are solved in general discrete time linear systems, via a reduction to equivalent open loop differential games. To prevent high order Riccati equations, found in some solutions, the state of the Hamilton-Jacobi system (HJS) resides in a quotient space of an auxiliary extended state space system. The dimension of that auxiliary space is equal t...

A solution of the discrete H ∞ smoothing problem is presented that lends itself well for generalization to sampled-data problems. The solution is complete and requires two sign-definite spectral factoriza-tions and one Nehari extension problem. A state-space equivalent is derived that is believed to be minimal. w e y v u H G v G y S-(a) w e y v u K G v G y-(b) FIG. 1.1. (a) Hold design. (b) Dis...
متن کاملYet another H∞ discretization
A new approach to the conversion of the sampled-data H problem to an equivalent pure discrete-time, lumped-variables counterpart, is presented. The approach is independent of controller causality constraints. In particular, it is applicable to problems, such as preview tracking and fixed-lag smoothing, where existing reduction methods fail. We demonstrate this by solving Open Problem no. 51 fro...
متن کاملEffects of a Partial Lag on the Achievable Performance of the H∞ Fixed-lag Smoothing
The fixed-lag smoothing problem with a partial lag is the problem in which the presence of the smoothing lag is allowed only in a part of estimation channels. This paper studies the effect of a partial smoothing lag on the achievable H ∞ performance in the continuous-time case. In particular, the limit of the achievable performance is established and the saturation of the achievable performance...
