Question

1. Steam-driven power generators rotate at a constant speed via a governor that maintains constant steam pressure in the turbine. In addition, load frequency control (LFC) is added to ensure reliability and consistency despite load variations or other disturbances that can affect the distribution line frequency output. A specific turbine-governor system can be described only using a unity feedback system with forward path $G_c(s)G_g(s)G_t(s)G_m(s)$ where: $G_g(s) = \frac{1}{0.2s+1}$ (governor TF) $G_t(s) = \frac{1}{0.5s+1}$ (turbine TF) $G_m(s) = \frac{1}{10s+0.8}$ (machine and load TF) and $G_c(s)$ is the LFC compensator to be designed. a. Design a controller to obtain an overshoot less than 5%, a settling time less than 2 seconds, and zero steady state error to a step input. To avoid
