CHAPTER
THEDESCRIBING FUNCTION TECHNIQUE
In Chap. 32, an on-off temperature-control system was studied in the phase plane. This work led to information about the limit cycle of the system as well as about the manner in which trajectories approached the limit cycle. Very often, this latter information about the transient approach to the limit cycle is unnecessary. Of primary interest to the designer are the amplitude and frequency of the limit cycle. The describing function method facilitates rapid, accurate estimates of these quantities without construction of the phase plane. In this chapter we shall study application of the describing function method to the analysis of the on-off controller for the temperature bath of Chap. 32. The treatment will be introductory only and largely confined to a single example. The purpose is to indicate the existence of the method and to show how it complements the phase-plane technique. The reader desirous of a more extensive treatment is referred to the text by Graham and McRuer (1961).
HARMONIC ANALYSIS
Consider the block diagram for the on-off control of the stirred-tank heater of Chap. 32, shown in dimensionless form in Fig. 33.1. In the following analysis, we omit the primes from the variables of Fig. 33.1. Our objective is to find the amplitude and frequency of the limit cycle that occurs in the control loop. The describing function method assumes that the error signal, in the limit cycle condition, is sinusoidal: E = Asinot 506 (33.1)

A glance at Fig. 32.9 shows that the error signal is not actually sinusoidal, since a sinusoidal signal appears as an ellipse in the phase plane. However, the difference between the actual limit cycle and an ellipse is not great, particularly if only the amplitude and frequency are of interest. If the error signal is sinusoidal, the relay output M can be derived from Fig. 33.2, where it can be seen from the input-output relations that M(t) is a square wave that lags e(t) by a time (l/o)sin- (Q/A). The time lag is due to the dead zone in the relay. Thus,
