The tourbillon is a mechanical device that was invented to improve the precision of old-fashioned pocket watches. These devices continually rotate the escapement, balance wheel, and spring to compensate for bias due to gravity. A high-quality modern mechanical watch can achieve a precision, referred to as rate error in the horological community, of 1 s per day, while a less expensive mechanical watch may attain a precision of 5 s per day. To place these figures in perspective, the precision of… Expand

Tourbillon was invented to cancel the gravity effect on the timekeeping accuracy of a mechanical watch. However, the complicated structure generates new errors. In the last decade,Expand


Origin and evolution of the anchor clock escapement
The escapement is a feedback regulator that controls the speed of a mechanical clock. The first anchor escapement used in a mechanical clock was designed and applied by Robert Hooke around 1657. ItsExpand
Limit cycle analysis of the verge and foliot clock escapement using impulsive differential equations and Poincaré maps
The verge and foliot escapement mechanism of a mechanical clock is a classical example of a feedback regulator. In this paper we analyse the dynamics of this mechanism to understand its operationExpand
Unscented filtering and nonlinear estimation
The motivation, development, use, and implications of the UT are reviewed, which show it to be more accurate, easier to implement, and uses the same order of calculations as linearization. Expand
A tutorial on particle filters for online nonlinear/non-Gaussian Bayesian tracking
Both optimal and suboptimal Bayesian algorithms for nonlinear/non-Gaussian tracking problems, with a focus on particle filters are reviewed. Expand
On the identification of variances and adaptive Kalman filtering
A Kalman filter requires an exact knowledge of the process noise covariance matrix Q and the measurement noise covariance matrix R . Here we consider the case in which the true values of Q and R areExpand
The role and use of the stochastic linear-quadratic-Gaussian problem in control system design
The emphasis of the paper is on the philosophy of the design process, the modeling issue, and the formulation of the problem; the results are given for the sake of completeness, but no proofs are included. Expand
Comparison and Analysis of Centralized, Decentralized, and Federated Filters
The numerical results presented support the hypothesis that better fault-tolerance performance can be achieved with a federated-decentralized filter than with a centralized filter approach. Expand
The pendulum clock: a venerable dynamical system
The steady-state motion of a weight-driven pendulum clock is shown to be a stable limit cycle. An explicit solution is obtained via Green functions. The pendulum amplitude is found to be a simpleExpand
Data Assimilation Using an Ensemble Kalman Filter Technique
The possibility of performing data assimilation using the flow-dependent statistics calculated from an ensemble of short-range forecasts (a technique referred to as ensemble Kalman filtering) isExpand
Watt steam governor stability
The physics of the fly-ball governor, introduced to regulate the speed of steam engines, is here analysed anew. The original analysis is generalized to arbitrary governor geometry. The well-knownExpand
