1. A method comprising: determining a set of solutions for an output feedback pole placement problem based on parameters of a physical system, the solutions being stable and well-conditioned to permit changes to the parameters of the physical system to be monitored, wherein determining the set of solutions comprises determining the set of solutions for a generalized output feedback pole placement problem based on the parameters of the physical system by: a) selecting a starting point for determining a solution based on the parameters of the physical system; b) determining the solution based on the starting point, assuming that the parameters are constant, based on a projective approach; c) storing for the solution, a solution matrix, eigenvalues of the solution matrix, one or more final matrices of a solution path of iterations leading to the solution, and eigenvalues of each final matrix of the solution path of the iterations leading to the solution; and, d) repeating a), b), and c) with different starting points for a number of times, such that the set of solutions are distinct; e) verifying the stability of each solution by: determining a condition number for the solution matrix for the solution; determining distances of one or more smallest of the eigenvalues of the solution matrix from an origin; f) selecting the set of solutions and matrices of the solutions that are well-conditioned; adjusting the physical system based on the solutions determined; acquiring updated parameters of the physical system at a plurality of time intervals; determining a set of updated solutions for the output feedback pole placement problem based on the updated parameters of the physical system by, for each solution, and based on a projective approach: determining whether the updated parameters of the physical system have changed relative to the parameters of the physical system; where the updated parameters remain unchanged, determining the updated solution as equal to the solution; and, where the updated parameters have changed, determining the updated solution based on one or more final matrices of a solution path of iterations that led to the solution; where the updated solution converges after iteration, archivally storing the solution, indicating that determination of the updated solution was successful, and updating the solution with the updated solution; and, where the updated solution does not converge after iteration, archivally storing the solution; indicating that determination of the updated solution was unsuccessful; removing the solution from the set of solutions such that the solution is not utilized; generating at least one new solution; adjusting the physical system based on the updated solutions determined; monitoring changes to the parameters of the physical system based on the updated solutions determined; and, detecting potentially critical changes in the physical system based on the updated solutions determined.
