The goal of this paper is to obtain stability of uncertain systems and to estimate the difference between solutions of a 'real' system with uncertain coefficients and/or delays and corresponding 'model' system with fixed coefficients and delays.

Of course, he immediately went on to say that its impact was uncertain indeed, hard to estimate, and in any event entirely manageable.
*A sense of probability, used to estimate uncertain outcomes by tracking how common one event is in relation to another.
An extended Kalman filter (EKF) has been designed to estimate uncertain parameters and un-measurable states.
An adaptation law is used locally to estimate uncertain impedance characteristics of the interaction forces between human and master and between slave and remote environment.
The use of fuzzy numbers (uncertain numbers) allows one to estimate the accuracy of the model's results even when the available data are not suitable for statistical analysis.
The main features of this approach include a nonlinear predictive filtering algorithm to estimate uncertain model errors and determine the spacecraft attitude by using attitude kinematics and dynamics, and a federated filtering algorithm to process measurement data from multiple attitude sensors.
First, a disturbance observer is employed to estimate uncertain disturbances, then the output torque and observed values are fed back to design the total amount cooperative tracking control protocol, which is used to coordinate traction torque output redundancy of each individual motor.
In the recent decades this approach has attracted researcher's attention to estimate uncertain parameters and to do risk analysis in oil and gas industry.
Moreover, Niimura [14] presented a fuzzy auto-regressive model to estimate uncertain electricity market prices in deregulated industry environment, and parameters are also obtained by solving linear programming problems.
