Question

 Below is given the forward transfer function of a unity-feedback system.
a) Determine the position, velocity, and acceleration error constants Kp, Kv, and Ka and the steady-state error for step, ramp, and parabolic inputs;
b) If possible, use a proportional controller to give a steady-state error for ramp input of e_ss(ramp) ≤ 0.01;

c) Determine the controller necessary to give zero steady-state error for a ramp input;
d) Determine the controller necessary to give zero steady-state error for a
parabolic input.

The image presents a transfer function in control systems, expressed in the Laplace domain: \[ G(s) = \frac{20(0.2s + 1)}{s(2s + 1)} \] ### Explanation: - **Numerator**: The numerator of the transfer function is \(20(0.2s + 1)\). This represents the zeros and gain of the system. - **Denominator**: The denominator is \(s(2s + 1)\), indicating the poles of the system. ### Components: 1. **Zeros**: A zero at \(s = -5\) derived from \(0.2s + 1 = 0\). 2. **Poles**: - One pole at \(s = 0\). - Another pole at \(s = -\frac{1}{2}\) from \(2s + 1 = 0\). This type of function is used to model and analyze the behavior of dynamic systems.
