When developing efficient and reliable computer-aided control system design (CACSD) tools for low-order robust control systems analysis and synthesis, the main issue faced by theoreticians and practitioners is the non-convexity of the stability domain in the space of polynomial coefficients, or equivalently, in the space of design parameters. In this paper, we survey some of the recently develo...

Induction Heating Furnaces are used extensively in industry. The basic principle is that induced eddy currents are used to heat a ferromagnetic material as it passes through a series of coils. Because of the importance of such systems, there has been on-going interest in their design and operation. Past work includes model development from physical principles and optimal design of operational p...

From a software design perspective, access control policies are requirements that must be addressed in a design. For example, access control policies are constraints that determine the type of access authorized users have on information resources. In this paper, we show how one can formulate access control policies as a policy model, formulate an access control aspect model that enforces polici...

The paper presents an improved design method of an optimal control system of a linear object with elastic coupling. The proposed method of the optimal control system design implies the selection of desired stability degree instead of the penalty matrixes selection procedure for the quadratic functional. The main idea of the method is the new state matrix utilization, which has its eigenvalues a...

This paper designed and developed a teaching robot three degrees of freedom manipulator based on Fischer creative combination model platform. Firstly, the overall structure of the robot was analyzed to determine the drive programs, and then the manipulator structure was assembled and established in accordance with the modular design approach. Finally, the robot control system was studied. This ...

A robust state feedback design subject to placement of the closed loop eigenvalues in a prescribed region of unit circle is presented. Quantitative measures of robustness and disturbance rejection are investigated. A stochastic optimization algorithm is used to effect trade-off between the free design parameters and to accomplish all the design criteria. A numerical example is given to illustra...

Acceptance control charts (ACC), as an effective tool for monitoring highly capable processes, establish control limits based on specification limits when the fluctuation of the process mean is permitted or inevitable. For designing these charts by minimizing economic costs subject to statistical constraints, an economic-statistical model is developed in this paper. However, the parameters of s...
