A two-Riccati equation solution to the H/sub /spl infin// control problem for periodic multirate systems is derived via the lifting method. The solution is expressed in terms of two algebraic Riccati equations. The causality constraints are represent

A state-space solution of the H∞ control problem for periodic multirate sampled-data systems is presented. The solution is characterized in terms of a pair of discrete algebraic Riccati equations with a set of associated matrix positive-definitenes

In distillation, a reliable model of the column is generally considered as a prerequisite for the design of efficient two-product control by multivariable methods. However, such models are often very hard to obtain. In fact, even very small identific

A class of dual-rate sampled-data systems is considered, where the sampling rate is asynchronously related to the rate at which the hold element is operating. Such asynchronous sampled-data systems are aperiodic, and hence the lifting technique, whic

The structure of the directionality in non-ideal (real) distillation is examined. The obtained knowledge of the directionality in distillation may be very useful when the two-point control problem is handled. A compensator structure to utilize this i

The concepts of process directionality and ill-conditionedness as commonly used in the literature might be confusing. Therefore, a refinement of the definition of process directionality is suggested. The refinement divides the concept of directionali

For the solution of the sampled-data H/sub /spl infin// problem various approaches have been introduced. A commonly used method is the lifting procedure, in which the problem is transformed into an equivalent discrete-time H/sub /spl infin// problem,
