Eigenvalue assignment of unified systems with slow and fast modes

摘要

A unified approach based on delta operator is presented to controlthe two-time scale, discrete-time or continuous-time systems. It isshown that such systems can be decomposed into a fast subsystem withlarge eigenvalues and a slow subsystem with small eigenvalues. Separateeigenvalues assignment is attained using independent feedback gains.Application of the technique is demonstrated via the problem ofindependently controlling the speed and torque of petrol enginedynamometer test rig
