Generalized input-output compensation of MIMO (multiinput, multioutput) systems with time delays is considered. It is shown that any of the three basic features of the Smith predictor can be extended to MIMO systems in the input-output configuration. A selection scheme that does not require the inverse of the plant transfer matrix is devised for plant delays in reducing diagonal delay elements in the decoupling response bound. It is believed that the scheme simplifies implementation of delay selection procedures. >read more

On the multivariable delay compensation
Nur Saygi,Alper Uraz +1 more
TL;DR: In this paper, a simplified delay compensator that needs no addition of extra time delays is developed, which is better than the existing two other methods when considering the responses at the outputs and the integral squared errors.

Linear multivariable systems
TL;DR: In this article, the authors propose a linear vector space representation of the state space and linear vector spaces of the linear operator representations of state vectors. But the state vector spaces do not have the same properties as the vector spaces used in this paper.

TL;DR: In this article, a multivariable time delay compensator for distillation is presented that combines the Ogunnaike-Ray compensator with the Smith predictor for a single delay.

Design of resilient processing plants—V: The effect of deadtime on dynamic resilience
Bradley R. Holt,Manfred Morari +1 more
TL;DR: In this paper, simple procedures are developed to determine how deadtime affects the best response achievable by a multivariable system, and the results can serve as the basis of an evaluation procedure for designs according to their operability characteristics (dynamic resilience).

Exploitation of time delays for improved process control
N. Shanmugathasan,R. D. Johnston +1 more
TL;DR: In this paper, a methodology for the identification of multivariable processes is developed that can achieve a higher level of controllability by increasing one or more time delays between the inputs and outputs.
