The press spokesman's system, which arose in the west, was introduced into China in 1983. It catered for China's diplomatism and external propagandizing. The press spokesman system was established broadly in the State Department, all the State Department's branches and local governments in 2003, which was accompanied by the comprehensive implementation of the new generation of central leaders' ideology of "governance for the people", the thorough revolution from "all-mighty government" to "serving government" and the lessons of the affair of SARS.

The system parameters are determined by optimizing an output-error cost function. To deal with the non-uniqueness of the fully parameterized state-space system, a projected gradient search algorithm is presented by restricting the update of the parameters to the tangent space to the manifold of observationally equivalent state-space systems. The sufficient condition to employ L-M algorithm for optimizing parameters is also introduced. The proposed hierarchical optimization identificationmethod includes two steps: First, the parameter search direction is determined by the proposed adaptive L-M projected gradient approach; Second, the optimum step size is computed according to a line search method.
