Abstract :
A design method is developed to ensure relative stability in terms of specific gain margins and phase margins of single input single output (SISO) discrete control systems with perturbed or adjustable coefficients. The method is a graphical parameter space technique based on fundamental Nyquist stability criteria through the method of D-partition.
