Controller Design for Linear Multivariable Systems
Measurement + Control, 1972 A method of designing controllers for multivariable systems is described which regards the problem from an implicit reference model point of view. The rules for the design are found to be very simple to apply and involve only proportional and integral ...

Predictive control of multivariable time-delay systems
MATEC Web of Conferences, 2017 In technical practice often occur multivariable processes with time delay. Time-delays are mainly caused by the time required to transport mass, energy or information, but they can also be caused by processing time or accumulation.

A Modified LQG Algorithm (MLQG) for Robust Control of Nonlinear Multivariable Systems [PDF]
Modeling, Identification and Control, 1993 The original LQG algorithm is often characterized for its lack of robustness. This is because in the design of the estimator (Kalman filter) the process disturbance is assumed to be white noise. If the estimator is to give good estimates, the Kalman gain

Optimal Control of Nonlinear Multivariable Systems [PDF]
Iranian Journal of Chemistry & Chemical Engineering, 2009 This paper concerns a study on the optimal control for nonlinear systems. An appropriate alternative in order to alleviate the nonlinearity of a system is the exact linearization approach.

Maximal imaginery eigenvalues in optimal systems [PDF]
Modeling, Identification and Control, 1991 In this note we present equations that uniquely determine the maximum possible imaginary value of the closed loop eigenvalues in an LQ-optimal system, irrespective of how the state weight matrix is chosen, provided a real symmetric solution of the ...
