The algorithm shapes the closed-loop gain without selecting weighting functions in H∞ control algorithm. Its core is to determine the final shape of the transfer function of the closed-loop system, the robust PID controller is directly constructed using parameters having engineering sense. The algorithm guarantees fundamentally that the designed controller has fine control performance and robustness.

The solution for the non-stationary system is obtained through the stationary disturbed system. The gradients of the system performances to all design variables are derived and they can be used to obtain optimal solution of the systems. More generally, if the performance of the system is a function of the solution of a set of generalized Lyapunov equation, then the gradients of the performance function to the coefficient matrices of the equation can be found in closed form.
