$3-$ Design a controller that controls the level of water $h$ in the tank with cross sectional area of $1m^2$ at $2\mathrm{.}0$ m $.$ Assume $q_i=80,q_0=50h(t),$ the motor inductance and friction are negligible and motor constant is $K_m=10N.\frac{m}{A}.$ It is required to see not a big overshoot in the response, since height of the tank is about $2\mathrm{.}5$ meter. Plot the response of the system. Assume inertia of the motor and the valve is $1kg-m^2(4$Opt$)$
