N2 - A loop-shaping approach for tuning Proportional-Integral-Derivative (PID) controllers is presented. A Glover-McFarlane controller is used to determine a target loop-shape that is approximated by a PID structure via the use of an LMI optimization method. If the approximation error from the minimization satisfies a standard small gain condition, then the tuned PID controller also shares the attractive robustness properties of the controllers. The entire design process is carried out in discrete-time assuming a discrete plant is available. Typical test cases are used to show the implementation of this method and the quality of the resulting closed loops.
