"feasible problem" is correct and usable in written English.
It can be used when describing an issue or challenge that is possible to overcome, usually with an effort, or when discussing the potential difficulties associated with a task. For example, "The team proposed several ideas to address the feasible problem of poor sales."
The paper presents and discusses feasible problem formulations and solution approaches for the constrained dynamic design of experiments.
Furthermore, we interpret that the presented controller design can be turned into a LMIs (linear Matrices Inequations) feasible problem which can be solved via existing softwares.
The sufficient condition of the existence of the augmented state feedback tracking guaranteed cost control is derived and converted to the feasible problem of the linear matrix inequality.
By constructing a network-status-dependent Lyapunov functional, a sufficient condition for the existence of the H∞ output feedback controller is formulated in the form of nonconvex matrix inequality, and the cone complementarity linearization (CCL) procedure is exploited to solve the nonconvex feasible problem.
However, the solution to this feasible problem is still not known in general.
In our approach, the observer designs are formulated as an LMI feasible problem, which is easily solved by standard convex optimization algorithms.
As mentioned before, P is a good mathematical wrapper for the set of feasible problems.
New interesting and feasible problems are expected to be found in future.
Suppose that ((x,y,lambda,w)) (feasible to problem (4)) is not a Pareto optimal solution to problem (4), then there exists a feasible point ((check{x},check{y},check{lambda },check{w})) to problem (4) (also feasible to problem (9)), satisfying Cx+C'yleq Ccheck{x}+C'check{y}, (12) which contradicts (11).
If ( x ¯, y ¯, λ ¯ ) is feasible to problem (4), then it is also a globally optimal solution to problem (4).
