Systematic Design of a Protective Controller in Process Industries by Means of the Boolean Differential Calculus
نویسنده
چکیده
Protective controllers prevent the occurrence of forbidden states in chemical processes. In this paper we present a new and systematic approach to design a protective controller with respect to the standardized concept in process industries`Safety of Process Plants Using Process Control Systems' 1]. The plant is modelled by means of nite automata. For an ef-cient solution of the controller synthesis task the system is described in the formalism of the Boolean Diierential Calculus. An algorithm for the synthesis of the protective controller is proposed. As an example it is applied to a simple subsystem of a chemical process.

Stability and Robust Performance Analysis of Fractional Order Controller over Conventional Controller Design
In this paper, a new comparative approach has been proposed for reliable controller design. Scientists and engineers are often confronted with the analysis, design, and synthesis of real-life problems. The first step in such studies is the development of a 'mathematical model' which can be considered as a substitute for the real problem. The mathematical model is used here as a plant. Fractiona...

Langevin equation for a nano-particle suspended in a laminar fluid flow was analytically studied. The Brownian motion generated from molecular bombardment was taken as a Wiener stochastic process and approximated by a Gaussian white noise. Euler-Maruyama method was used to solve the Langevin equation numerically. The accuracy of Brownian simulation was checked by performing a series of simulati...

In this paper, by combining fractional calculus and sliding mode control theory, a new fractional order adaptive terminal sliding mode controller is proposed for the maximum power point tracking in a solar cell. To find the maximum power point, the incremental conductance method has been used. First, a fractional order terminal sliding mode controller is designed in which the control law depend...
