Nonlinear ODE's of Damped Driven Pendulum or not?

I am having some confusions with regards to my problem, whether or not the differential equations presented to me are inclined to damped driven pendulum. From the differential equations given, I can see that these equations are part of the convection equations made my Lorenz dubbed as Lorenz equations. Are the nonlinear ODE's in this problem related to the damped driven pendulum or not?
