External acceleration elimination for complementary attitude filter

2017 IEEE International Conference on Information and Automation (ICIA), 2017
Generalized complementary filter (GCF) is an attractive solution for data fusion in attitude and heading reference system (AHRS) and inertial measurement unit (IMU), mainly because its computational efficiency. However, since the accelerometer in AHRS and IMU is sensitive to both the gravity and external acceleration, the performance of GCF will be ...

Complementary Filter Pairs

2009
Digital filters with complementary characteristics find many applications in practice. In this chapter, we concentrate on the properties and construction of complementary filters and filter pairs. An important application of complementary property is deriving a new transfer function from the existing one.

Time-varying complementary filtering for attitude estimation

2011 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2011
Complementary filtering (CF) is a well known method that can effectively fuse a gyroscope and accelerometer measurement in order to robustly estimate the attitude of a rigid body in a planar single degree of freedom (DOF) setting. The attitude can be estimated individually by either integrating the gyroscope measurement or by calculating the inverse ...

Generalized doubly complementary IIR digital filters

Signal Processing, 1992
The authors examine the properties of weighted complementary IIR filters. Either real or complex allpass subfilters are utilized. The classical odd-order lowpass designs can be realized as a parallel connection of two real or complex conjugate allpass filters. Also, a complementary filter pair can be implemented at the cost of a single filter.

Filter bank representation of complementary sequence pairs

2012 50th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2012
A unique decomposition of arbitrary pairs of complementary sequences (including binary, polyphase and QAM) based on paraunitary matrices is presented. This decomposition allows us to describe the internal structure of any sequence pair of length N using basic paraunitary matrices defined by N complex coefficients named omega vector.

A Comparison of Complementary and Kalman Filtering

IEEE Transactions on Aerospace and Electronic Systems, 1975
A technique used in the flight control industry for estimation when combining measurements is the complementary filter. This filter is usually designed without any reference to Wiener or Kalman filters, although it is related to them. This paper, which is mainly tutorial, reviews complementary filtering and shows its relationship to Kalman and Wiener ...

A complementary pair LMS algorithm for adaptive filtering

1997 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2002
This paper presents a new algorithm that can solve the problem of selecting appropriate update step size in the LMS algorithm. The proposed algorithm, called a complementary pair LMS (CP-LMS) algorithm, consists of two adaptive filters with different update step sizes operating in parallel, one filter re-initializing the other with the better ...

State-Space Analysis of Power Complementary Filters

IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2007
This paper presents a new analysis of power complementary filters using the state-space representation. Our analysis is based on the bounded-real Riccati equations that were developed in the field of control theory. Through this new state-space analysis of power complementary filters, we prove that the sum of the controllability/observability Gramians ...
