WebThe Ziegler–Nichols method is too aggressive for many industrial control systems. For example, for a proportional controller, the method specifies a GM of just 6 dB, compared with the 12 dB in the P controller tuned earlier in this chapter (Figure 6.5 ). In general, the gains from Ziegler–Nichols will be higher than from the methods presented here.
