Stabilization of Unstable Second-Order Delay Plants under PID Control: A Nyquist Curve Analysis

Time delays arise in various components of control systems, including actuators, sensors, control algorithms, and communication links. If not properly taken into consideration, time delays will degrade the closed-loop performance and may even result in instability. This paper studies the stabilizati...
