Linear Quadratic Integral controller for position control

Linear Quadratic Integral (LQI) controller for position control of PMDC Motor

The simulation shows how we can implement a Optimal FSFB LQI controller in simulink for tracking. It uses 3rd order system to control one output (For MOs use additional integrators in Mux) i.e. position (Tracking system). The parameters are not included on purpose. User can use Matlab command LQI to get gain values or can use LQR with modified A, B, C matrices for better understanding the calculations.
