In order to make these approaches tractable for systems containing a very large number of subsystems, constraints on the Lyapunov matrix and the multiplier matrices are introduced that render the complexity of analysis and controller synthesis smaller and in best case independent on the number of subsystems. Those assumptions have to be paid for with conservatism, which is investigated in this work. It is proven that the conservatism is not reduced if either only the Lyapunov or only the multiplier matrices are constrained, when compared with having constraints on both simultaneously.es1474-6670201428602865ElsevierComplexity reductionConservatismDistributed controlLarge-scale systemsLinear parametrically varying (LPV) methodologiesInformatikConference Paper10.3182/20140824-6-za-1003.00712Other
