Rate of control minimization. • LQR design with prescribed degree of stability. ○ LQR for command tracking. ○ LQR for inhomogeneous systems. The theory of optimal control is concerned with operating a dynamic system at minimum cost. (linear–quadratic–Gaussian) problem. Like the LQR problem itself, the LQG problem is one of the most fundamental problems in control theory. Lecture notes on. LQR/LQG controller design. Jo˜ao P. Hespanha.

The LQR algorithm reduces the amount of work done by the control systems engineer to optimize the controller. The case where the system dynamics are described by a set of linear differential equations and the cost is described by a quadratic function is called the LQ problem.

The automated translation of this page is provided by a general purpose third party translator tool. The settings of a regulating controller governing either a machine or process like an airplane or chemical reactor are found by using a mathematical algorithm that minimizes a cost function with weighting factors supplied by a human engineer. The cost function is often defined as a sum of the deviations of key measurements, desired altitude or process temperature, from their desired values.

Often this means that controller construction will be an iterative process in which the engineer judges the “optimal” controllers produced through simulation and then adjusts the parameters to produce a controller more consistent with design goals.

Difficulty in finding the right weighting factors limits the application of the LQR based controller synthesis.

Lr algorithm thus finds those controller settings that minimize undesired deviations.
