In this technical note, an approximate tracking and disturbance rejection problem is solved for the class of exponentially stable well-posed infinite-dimensional systems by invoking a simple sampled-data low-gain controller (suggested by the internal model principle). The reference signals are finite sums of sinusoids and the disturbance signals are asymptotic to finite sums of sinusoids.
