Relay feedback analysis is a powerful tool for identifying and controlling the dynamics of nonlinear systems. It is based on the principle of using a relay as a feedback element in a closed-loop system. The relay switches between two states, "on" and "off", depending on the error signal between the desired output and the actual output. The switching action of the relay introduces a nonlinearity into the system, which can be exploited to identify and control the system's dynamics.

Benefits of Relay Feedback Analysis

Relay feedback analysis offers several benefits over other methods of system identification and control. First, it is a non-parametric method, which means that it does not require a priori knowledge of the system's dynamics. This makes it a versatile tool for a wide range of systems. Second, relay feedback analysis is a robust method, which means that it is not sensitive to noise and disturbances. This makes it a reliable method for identifying and controlling systems in real-world applications.
