The full form of LQR is Linear Quadratic Regulator.
Understanding the Linear Quadratic Regulator (LQR)
The Linear Quadratic Regulator (LQR) is a core concept in optimal control theory. According to our reference, it is likely the most important and influential result in the field to date.
Key Aspects of LQR
-
Stabilization: LQR is fundamentally designed for stabilizing a time-invariant linear system to the origin (i.e., bringing the system to a desired equilibrium state).
-
Optimality: LQR provides a method for calculating the optimal control input needed to achieve stabilization.
-
Applications: Due to its effectiveness and relative simplicity, LQR is widely used in various control system applications, from robotics to aerospace.
