The advent of fast, simple to use, interactive simulation languages makes this simple method attractive as a first try. The good results which simple techniques can achieve are shown by application to a 10th order model of an electric arc furnace electrode position controller. This is reduced to a sixth order model by the simple technique, and also by a mathematically rigorous plane-projection method. Comparison of the resulting models shows that the one produced simply is just as good as, and avoids the mathematical complexity of, other techniques. 收起
