Discrete-Time Exact and Approximate Dynamic Inversion for Settle Performance
Single-track hard disk drive (HDD) seek performance is measured by settle time, ts, defined as the time from the arrival of a seek command until the measured position reaches and stays within an acceptable distance from the target track. In this paper, we show the effective use of feedforward dynamic inversion, coupled with an aggressive desired trajectory yd, to achieve high performance settle...
متن کاملOn Approximate Dynamic Inversion
Approximate Dynamic Inversion has been established as a method to control minimum-phase, nonaffine-incontrol systems [1]. In this report, we re-state the main results of [1], clarify some minor notational errors, and prove the same results in an expanded form. In the large, the main results of [1] still stand. The development follows [1] closely, and no novelty is claimed herein. The purpose of...
متن کاملA Kalman Filter-based Stable Dynamic Inversion for Discrete-time, Linear, Time-varying Systems
In this paper the problem of estimating an unknown input for discretetime, non-minimum phase, multivariable, linear time-varying systems (LTV) is considered. The initial condition of the plant may be unknown and stochastic process and measurement noise are included. The input signal is modelled as a random walk with drifts. Then it is estimated using a Kalman filter for a uniformly detectable a...

15 صفحه اولMinimal Order Discrete-time Nonlinear System Inversion
The left-inverse system with minimal order of a discrete-time nonlinear system is studied in a linear algebraic framework. The general structure of the left inverse is described. Two algorithms are given for constructing left-inverse systems having minimal order.
