LQR (linear quadratic regulator) is a linear quadratic regulator whose object is a linear system given in the form of state space in modern control theory, and the objective function is a quadratic function of the object state and control input. The LQR optimal design refers to the design of the state feedback controller K to make the quadratic objective function J take the minimum value, and K is determined by the weight matrix Q and R uniquely, so the choice of Q and R is particularly important.
