“…The stability filter G f (z) is used to ensure the overall system is stable after the introduction of RC. It is often designed as the inverse of the closed loop transfer function or a zero phase error tracking compensator [16]. A time advance unit has been adopted here as a simple structure for G f (z).…”

“…An alternative approach is presented in Section 3.2. In this section is described that, since the harmonics in the input signal can be treated as periodic disturbances and since their period-time is exactly known, significant rejection is possible using repetitive control [Hara, Yamamoto, Omata, & Nakano, 1988, Tomizuka, Tsao, & Chew, 1988, Yau, & Tsai, 1999. Both approaches will be demonstrated with a simulation in order to objectively evaluate their effectiveness under well controlled circumstances.…”

Measuring the higher order sinusoidal input describing functions of a non-linear plant operating in feedback

In this paper two measuring techniques are presented for measuring the Higher Order Sinusoidal Input Describing Functions (HOSIDF) of a non-linear plant operating in feedback. The HOSIDF relate the magnitude and phase of the harmonics of the periodic response of a non-linear system to the magnitude and phase of the sinusoidal excitation. In a controlled system the harmonics generated by the non-linear system will be fed back to the input changing the sinusoidal excitation into a harmonic excitation. The first method applies linear techniques to compensate the bias caused by the harmonic components in the excitation signal. The second method uses a modified repetitive control scheme to suppress the harmonic components in the excitation signal. The effectiveness of both methods is tested in simulations of a mass subjected to Coulomb friction, Stribeck-effect and hysteresis in the pre-sliding regime. The friction forces are modeled with the modified Leuven friction model. The results are compared with the HOSIDF simulated under open loop condition. Both methods prove able to produce reliable results.
