The problem is discussed of establishing whether the optimal constant control of a given plant (with respect to a specified performance index and subject to equality and/or inequality constraints) can be improved by cycling. A frequency domain approach is followed in order to establish a general condition, which, in the particular case of single-input systems, admits a simple geometric interpretation. Connections with high frequency and slowly varying periodic control problems are also pointed out.
