A Self-Contained Cylinder Drive with Indirectly Controlled Hydraulic Lock [PDF]
Modeling, Identification and Control, 2020 This paper presents a self-contained pump-controlled hydraulic linear drive including an innovative load holding sub-circuit. For safety critical applications such as crane manipulators, locking valves or load holding valves are enforced by legislation ...

Hard constraints in control state variables of multivariable nonlinear processes resolved by elementary nonlinear decoupling [PDF]
Modeling, Identification and Control, 1998 A model based control strategy for nonlinear multivariable processes having hard constraints on both control and state variables, is derived based upon the concept of Elementary Nonlinear Decoupling (END). In END a property space is defined which has the

Multivariable Feedback Control of Nuclear Reactors [PDF]
Modeling, Identification and Control, 1982 Multivariable feedback control has been adapted for optimal control of the spatial power distribution in nuclear reactor cores. Two design techniques, based on the theory of automatic control, were developed: the State Variable Feedback (SVF) is an ...

Fractal and Fractional, 2020 Multiple-input multiple-output (MIMO) systems are usually present in process systems engineering. Due to the interaction among the variables and loops in the MIMO system, designing efficient control systems for both servo and regulatory scenarios remains

Multivariable PID control by decoupling [PDF]
International Journal of Systems Science, 2014 This paper presents a new methodology to design multivariable PID controllers based on decoupling control. The method is presented for general n×n processes. In the design procedure, an ideal decoupling control with integral action is designed to minimize interactions.

Multivariable Control of Distillation Column
IFAC Proceedings Volumes, 1995 Abstract Three methods for discrete control of distillation column are compared. The distillation column, separating binary mixture of methanol-water, is regarded as a two inputs - two outputs system. The controller design for all methods is made by the pole placement method, but three different variants are used: The multivariable case, the ...

Learning Output Reference Model Tracking for Higher-Order Nonlinear Systems with Unknown Dynamics
Algorithms, 2019 Linearly and nonlinearly parameterized approximate dynamic programming approaches used for output reference model (ORM) tracking control are proposed. The ORM tracking problem is of significant interest in practice since, with a linear ORM, the closed ...

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.,

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.
