Difficulty in finding the right commabde factors limits the application of the LQR based controller synthesis. The cost function is often defined as a sum of the deviations of key measurements, desired altitude or process temperature, from their desired values.

The LQR algorithm reduces the amount of work done by the control systems engineer to optimize the controller. The output S of lqr is the solution of the Riccati equation for the equivalent explicit state-space model:.

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 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.

However, the engineer still needs to specify the cost function parameters, and compare the results with the specified design goals. In addition to the state-feedback gain Klqr returns the solution S of the associated Riccati equation.

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.
