The gain of the plant can be included in the numerator of the transfer function block. Find the Simulink model attached that simulates a second order plant with time delay and PID controller block to … Web2. The stability of the system considering the cable’s resistance and communication time delay is analyzed, and stability conditions are provided. First, the stability condition of the system with no communication is derived. Second, the stability condition of the system without time delay is obtained based on the singular perturbation theorem. light reflecting loose setting powder
