AE 353 Aerospace Control Systems Spring 2010 HW#1 (Assigned 1/25, Due 2/5 in class) Please write your answers legibly. Problem 1: Why feedback control? (50%) 1.1) Select an example of a closed-loop system that you are familiar with (e.g., aircraft, spacecraft, robot, but something different from cruise control). Draw a simple block diagram, similar to the figure below. For the system of your choice, specify the physical input, the physical output, and a possible source of disturbance and noise. Also, write down the physical devices that constitute “plant”, “sensors”, “controller”, and even “reference input” (e.g., stick

The difference is called the steady-state error, and one of the objectives of feedback is to minimize the quantity. In Prob. (1.4), what happened to the steady-state error as you vary the gain K? Is your answer different for the two plants? Problem 2. Use Laplace Transform (25%) . Problem 3) Use Laplace Transform (25%)...
