Abstract :
Integral-type optimal servosystems based on the application of the continuous or discrete time optimal regulator theory are analyzed from viewpoints of the norms of complementary sensitivity, and the sensitivity and disturbance functions. The analyses are performed on cases with and without feedforward control laws. Furthermore, the influences and the characteristics of the feedforward control laws which minimize the quadratic performance indices are examined
