Well, LQR is a linear control law. It's in the name: Linear Quadratic Regulator.
But as noted in my comment above, linear controllers can be used to control nonlinear systems under certain circumstances.
p.s. btw, having more states in the model does not linearize a nonlinear system per se. Only nonlinear transformations like log-transforms are capable of linearizing a system.
