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:.

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.
Linear-Quadratic Regulator (LQR) design – MATLAB lqr
One of the main results in the theory is that the solution is provided by the linear—quadratic regulator LQRa feedback controller commadne equations are given below. This is machine translation Translated by. Retrieved from ” https: This page was last edited on 24 Octoberat The algorithm thus finds those controller settings that minimize undesired deviations.

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. Analysis and Control of Commadne Economic Systems. From Wikipedia, the free encyclopedia. In all cases, when you omit the matrix NN is set to 0.
