Optimal damping seeks to determine a vector of damping coefficients that
maximizes the decay rate of a mechanical system's response. This problem
can be formulated as the minimization of the trace of the solution to a Lyapunov
equation whose coefficient matrix depends on the damping parameters,
which must satisfy nonnegativity constraints for physical relevance.
We propose two fast algorithms for solving this resulting nonlinear
optimization problem under nonnegativity constraints and demonstrate their computational
efficiency.
