This paper deals with an efficient algorithm for optimization of the solution of the parameter-dependent Sylvester equation (A"0-vC"1C"2^T)X(v)+X(v)(B"0-vD"1D"2^T)=E, where A"0, B"0 are mxm and nxn matrices, respectively. Further, C"1 and C"2 are mxr"1, D"1 and D"2 are nxr"2 and X, E are mxn matrices, while v is real parameter. For optimization we use the following two optimization criteria: Tr(X(v))-min and @?X(v)@?"F-min. We present an efficient algorithm based on derived formulas for the trace and for the Frobenius norm of the solution X as functions v-Tr(X(v)) and v-@?X(v)@?"F as well as for derivatives of these functions. That ensures fast optimization of these functions via standard optimization methods like Newton's method. A special case of this problem is a very important problem of damper viscosity optimization in mechanical systems.
