The results revealed that the conversion was 92.4% when aniline concentration was 1 mol/L, feeding temperature was 25℃ and residence time was 11 s. With feeding temperature being the main factor, the effect of residence time decreases successively. The diazotization anomalies could be caused at aniline concentration above 1.5 mol/L. The proper feeding temperature which can lead to the highest conversion was 20~30℃.

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.
