Consider the radial tracking problem of a CD player lens. The block diagram for such a system is shown in the figure.what's a,b,c, and d? Consider the radial tracking problem of a CD player lens. The block diagram for such a system is shown in the figure. Here \( y \) is the radial position, \( d \) is the external disturbance on the position and \( u \) is the control signal for the lens. Transfer function for the CD lens between the control \( u \) and the radial position is estimated as \( \mathrm{G}_{\mathrm{p}}(\mathrm{s})=\frac{-40000 \mathrm{~s}+2.5 \cdot 10^{9}}{\mathrm{~s}^{2}+200 \mathrm{~s}+95000} \). a) Suppose a \( \mathrm{P} \) control strategy is used, i.e., \( \mathrm{G}_{\mathrm{c}}(\mathrm{s})=\mathrm{K} \). Show that if \( \mathrm{K} \) is increased from zero, the system will go unstable after a certain \( \mathrm{K} \) value. Find that \( \mathrm{K} \) value. b) Find the steady state error for a unit step disturbance input for the \( \mathrm{K} \) value you found in part (a). c) Use \( \mathrm{G}_{\mathrm{c}}(\mathrm{s})=0.2 \frac{1+0.002 \mathrm{~s}}{1+0.1 \mathrm{~s}} \frac{1+0.00067 \mathrm{~s}}{1+0.0002 \mathrm{~s}} \) as a controller. Plot the unit disturbance response of the system using MATLAB, and estimate the settling time and the steady state value from the plot. d) One of the causes of disturbance in CD players is the eccentricity of the CD, which results in a sinusoidal disturbance on the radial position. Using MATLAB, simulate the disturbance response of the system for \( \mathrm{d}(\mathrm{t})=0.1 \sin (10 \mathrm{t}) \). Hint: You can try using MATLAB Control System Toolbox functions feedback, step, tf, etc. in your solutions.
