Optimal synthesis of control systems
Proceedings of the 40th IEEE Conference on Decision and Control (Cat. No.01CH37228), 2002A new approach to the synthesis problem of optimal feedback controls is proposed. An algorithm of operating optimal controllers able to calculate values of optimal feedbacks during each particular control process in real time is described. Under incomplete and inexact information, a problem of optimal observation is introduced.

Synthesis of reliable control systems
Proceedings of the 1997 American Control Conference (Cat. No.97CH36041), 1997The problem of reliable control against arbitrary sensor and actuator failure is addressed. It is shown that, for a class of open loop stable, minimum phase systems, complete reliability can always be achieved through the use of a PID/sup r/ controller which induces a diagonal dominant condition in the DC gain of the transfer matrix while preserving ...

Control circuit synthesis system
Systems and Computers in Japan, 1986AbstractThis paper presents a systematic and automatic synthesis procedure based on the behavior specifications and the data path. The system automatically determines the control of the data path components and quasiminimizes the hardware complexity of the control circuit.

Synthesis of Process Control Systems
IEEE Transactions on Systems, Man, and Cybernetics, 1978A systematic logical procedure for the synthesis of control systems for processes is presented. The approach is based on a causal modeling of processes, represented by the cause-and-effect graph. Control systems are generated by propagating the constraint variable on the cause-and-effect graph of the process.

Control synthesis in (max,+) systems
EFTA 2003. 2003 IEEE Conference on Emerging Technologies and Factory Automation. Proceedings (Cat. No.03TH8696), 2004Control synthesis is an important problem in the field of discrete event systems. The subclass of Timed event graphs can be modelled by state equations using the (max,+) algebra. This document proposes an approach of constraint propagation type using Kleene's star in order to solve the control synthesis problem.

Multivariable control system synthesis
Transactions of the American Institute of Electrical Engineers, Part II: Applications and Industry, 1958An important problem in the field of multivariable control systems is the design of suitable feedback and series compensation elements which, when added to a given system, result in an over-all system with improved characteristics. This improvement may apply to the behavior of the controlled variables, to the disturbance response of the system, or to ...

Control of vector discrete-event systems. II. Controller synthesis
IEEE Transactions on Automatic Control, 1994Summary: It was shown in Part I [ibid. 38, 1214-1227 (1993; Zbl 0784.93007)] that vector discrete-event systems (VDES) provide compact models for a useful class of control systems. In this sequel, it is shown that associated control synthesis problems of Ramadge-Wonham type can be efficiently solved under mild technical restrictions, using elementary ...

Control Synthesis for Čaplygin Polynomial Systems
Acta Applicandae Mathematica, 2000Powerful analytic tools have been developed in order to investigate controllability of nonlinear systems. But, on the other hand, there are no effective synthesis procedures. In other words, we can (more or less) easily determine whether an arbitrary nonlinear system can be steered from any given point into certain prescribed state -- but are unable ...

Performance-aware scheduler synthesis for control systems
Proceedings of the ninth ACM international conference on Embedded software, 2011We consider the problem of designing a cyber-physical system where several control loops share the same architectural resources. Typically, the design of such systems proceeds in two steps. In the platform independent step, for each control loop in the system, the control designer calculates a control law and a sampling time that together ensure that ...

A control system is designed to meet certain performance requirements, which usually include system stability, steady-state accuracy, dynamic accuracy, and insensitivity to parameter changes. These performance requirements can be expressed either in terms of the system transient response (quantities such as the maximum overshoot, rise time, settling ...
