Figure 4

Frequency-domain errors corresponding to the MLP and FIR filter-based controllers over a range of reference signal magnitudes x_mag, averaged over 5 instances of controller training. Black: Disturbance; Blue: FIR controller error; Red: MLP controller error. All signals used to calculate PSD estimates are normalised with respect to the RMS of the disturbance signal.
