Abstract :
A laboratory exercise on a compensation technique using flexible digital tools is presented. The method for the generation of a special kind of switching-type double-valued characteristic using a microprocessor is described. This characteristic is used to stabilize and improve the system performance of a linear control system. A mathematical analysis leads to conclusions about the determination of the nonlinear element characteristics to improve the system response. An approach based on the describing function (DF) method leads to a compensation technique in the complex plane. The circuit, the theoretical analysis, and experimental results for the compensation of a double integrator plant are presented
