Modern automatic motion control systems of marine vehicles operate in different dynamic modes defined by the specific assignment of command signals and external disturbances acting on the control object. For each of these modes in the systems' design stage a set of requirements, conditions and restrictions which must be strictly fulfilled is formed. This… (More)
The plasma control system for the Mega Amp Spherical Tokamak, MAST , being constructed at Culham as a scaled-up successor to the highly successful START, must cope with unique and challenging features. The PF coils inside the vacuum tank produce strong flux gradients near some of the magnetic diagnostics, and stray flux from the solenoid contributes… (More)
This paper is devoted to a particular case of H∞-optimization problem for LTI systems with scalar control, external disturbance and measurement noise. This problem can be numerically solved with the help of the well-known universal approaches based on Riccati equations, LMI or maximum entropy technique. Nevertheless, in our opinion there exists a… (More)
Report is devoted to basic conceptions of computer technologies and systems application in the wide area of control systems and processes investigation and design. A special attention is focused on the ideology of optimization approach connected with the problems of control systems modeling, analysis, and synthesis. Some questions of digital control laws… (More)
The problem of current and shape plasma stabilization in tokamaks is considered. The scheme of stabilization based on the H2 and H-infinity optimization problems solutions is proposed.
The problem of external disturbances rejection is considered for control systems of marine ships steered by autopilot under the action of sea wave disturbances and bias terms. The essence of the problem is to find mathematical models of adjustable corrective items for control law with a special structure, to provide desirable values of correspondent… (More)
The problem of plasma current and shape stabilization system design in tokamaks is considered. The approach for plasma stabilization based on parameter optimization problem solution for searching state-feedback control is proposed. It is applying for plasma current and shape controller synthesis for ITER tokamak.
This paper is devoted to H2-optimization of linear time invariant (LTI) systems with scalar controls and external disturbances. It is supposed that the intensities of control actions are not given initially for all channels of control. In conformity, a joined problem of H2-optimal synthesis is posed including allocation of control actions. To solve this… (More)
