Abstract
The frequency response describes the steady-state behavior of a control system to sinusoidal inputs across varying frequencies and serves as an effective tool for system design. In closed-loop reset control systems, frequency response analysis reveals two distinct scenarios: systems with two reset instants per steady-state cycle and systems with multiple (more than two) reset instants per cycle. Existing frequency response analyses often assume only two reset instants, which can result in inaccuracies for systems with multiple resets. Additionally, multiple resets can generate high-magnitude higher-order harmonics, which may result in system performance degradation. This study introduces a novel method to identify conditions where only two reset instants occur in closed-loop reset systems. This method allows designers to avoid multiple-reset actions during the system design phase. By ensuring the system operates with only two resets per cycle, this method enhances the accuracy of frequency response analyses that assume this condition. The effectiveness of the proposed method is validated through simulations and experimental tests on a precision motion system.
