✦ Synopsis

tance is the question of how many restrictions can be placed on the structure of the compensator, which makes a system integral controllable and robust. Any restrictions imply a simplified control structure and are, therefore, practically significant.Morari [6] has discussed the implications of the results derived here for nonlinear sy_stems. He has shown that for systems with input multiplicities, det (G) of the linearized system changes sign. The resulting robustness problems cannot be removed with linear compensators.
