Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely:  consider a single-input-single-output (SISO) nonlinear system that has a ll-defined normal form with asymptotically stable zero dynamics. Using only knowledge of the relative degree and the sign of the high-frequency gain,  design an output feedback integral controller that asymptotically regulates the output to a bounded time-varying reference signal with a constant limit.  give regional as ll as semi-global results.  also show that, for relative degree one and two systems, the proposed integral controller reduces to the classical PI and PID controllers, respectively.
