Changing the damping ratio of a second-order linear system, such as a robotic arm, typically involves adjusting system variables, including natural frequency. Directly altering the damping ratio alone is challenging, as it often requires simultaneous changes to other parameters. The system equations indicate that modifications to one variable can affect both damping and natural frequency. Achieving a precise adjustment with a single control parameter is not straightforward. Overall, careful consideration of multiple variables is essential for effective tuning of the system's dynamics.
