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 ...

FUZZY CONTROL FOR MULTIVARIABLE SYSTEMS
IFAC Proceedings Volumes, 1983 Abstract In this paper a fuzzy control algorithm for regulator control of multivariable systems based on a state space model of the system is introduced. Its application to several linear systems is illustrated and compared with systems controlled by means of linear feedback laws as obtained via an INA-design or linear output feedback.

Maximally Robust Controllers for Multivariable Systems [PDF]
SIAM Journal on Control and Optimization, 2000 The problem of designing an internal stabilizing controller \(K\) which stabilizes \(G\) and \(G+\Delta\) for all \(\Delta\)'s with \(\|\Delta\|< r\) is a deeply studied problem, and it is well known how to design \(K\) and what is the largest radius \(r\). The authors show that there is a worst case direction in the maximal ball of uncertainties, i.e.,

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.

Recursive Algorithms for Multivariable Output-Error-Like ARMA Systems
Mathematics, 2019 This paper studies the parameter identification problems for multivariable output-error-like systems with colored noises. Based on the hierarchical identification principle, the original system is decomposed into several subsystems.

Phase Transition of Multivariate Polynomial Systems [PDF]
Mathematical Structures in Computer Science, 2007 A random multivariate polynomial system with more equations than variables is likely to be unsolvable. On the other hand, if there are more variables than equations, the system has at least one solution with high probability. In this paper we study in detail the phase transition between these two regimes, which occurs when the number of equations ...

Real-Time Experimental Benchmarking of Control Strategies for a Coupled 2-DOF Helicopter
EngThis paper presents a real-time experimental comparison of four control strategies—PID, Fractional-Order PID (FOPID), Fuzzy PID/PD, and Model-Free Control (MFC)—applied to trajectory tracking of a coupled 2-DOF Quanser Aero 2 helicopter.

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.
