Question

Question asked by Filo student

In the physical scenario to be modeled in the "Modeling Springs with Python" lab, the force of friction depends on |object.v| (norm of object.v). Friction does not depend on the object's velocity in this scenario. v = object.v. -|object.v| (norm of object.v).

Question 1

Hard

A copper wire of length

5 cm

carries a current of density

j = 1 A (mm)^{- 2}

. The density and molar mass of copper are

9000 Kg m^{- 3}

and

63 gmol^{- 1}

. Each copper atom contributes one free electron. The temperature of the wire is

2 7^{\circ} C

. Estimate the (average) distance travelled by a free electron during the time it moves from one end of the copper wire to the other end. Assume that thermal motion of electrons are similar to that of molecules of an ideal gas.

Question 1

Proportional-Integral-Derivative controller with velocity feedback: The normal situation is for a load to be present in order for the motor to perform a task. The cancellation of the steady state error which the load causes while leaving performance relatively unaltered is a must if the motor is to be useful. PID (Proportional-Integral-Derivative) control is a common approach in industry to eliminate/reduce steady state error. PID control works by feeding forward the integral of the position error as shown in figure-4. The parameter space needed to manage the quality of the motor response is now three-dimensional, having the tuning variables Kp, Kv, and Ki which form its axis. DC Motor Figure-5: Proportional-Integral position servo with position and velocity feedback The steps for investigating the use of PID control in canceling the effect of the load on the response are:

Derive the transfer function of the system in figure-5.
Mathematically derive the region of stability for the system and plot it in the 3-D (Kp, Kv) parameter space.
Select three values for Ki (high, medium, and low) to be used with the PID controller. These values should be selected so that when they are added to the critically damped set of Kp-Kv obtained earlier, the results in a stable response.
For one of the load levels you selected earlier, use Simulink to obtain the quantities below for each value of the selected Ki parameter and the critically damped Kp-Kv curve. Plot each quantity as a function of Kp. Compare the results to the one obtained before:

Question 4

From Mcquarrie 4-14 4-14. The rotational energy of diatomic molecules can be well approximated by a quantum mechanical rigid rotor. According to Eq. (1-32), the energy levels depend upon the moment of inertia, which for a diatomic molecule is 0(10-4 g-cm2). Calculate and plot the population of rotational levels of a diatomic ideal gas at 25C. Do not forget to include the degeneracy 2J+1.
