Nussbaum function is used to deal with the unknown sign of uncertain control coefficient and the possible controller singularity problem.
The interday quality control coefficient of variation was 3.7%%.
The spectral radius of the control coefficient matrix is used to relax the nonsingular assumption of the control coefficient matrix.
where ε i denotes back-off power control coefficient for the ith antenna.
Switched nonlinearities, switched control coefficient functions, and external disturbances are assumed to be unknown.
Then the relationship between the dynamic envelope and the control coefficient or pilot command is obtained, and the result shows that the dynamic envelope can be enlarged with the change of control coefficient.
Switched nonstrict-feedback nonlinearities, switched control coefficient functions, and external disturbances are considered and assumed to be unknown.
It is shown that regulation can be achieved in the case of an unknown control coefficient and uncertain constant parameters.
Here, γ = diag [ γ 1, γ 2, …, γ K ] represents the power control coefficient matrix formulated for imposing the transmission power constraint.
The adaptive state-feedback boundary control design is investigated for a class of heat equations with uncertain control coefficient and boundary disturbance.
The extent of control of enzyme concentration on the flux is expressed as the flux control coefficient and is estimated directly by experiments and by modeling techniques.
