program control OF CURRENT BUILDUP IN TOKAMAK

JOURNAL OF NUCLEAR SCIENCE AND TECHNOLOGY 1983年第4期20卷 302-309页

A program control method is formulated and discussed with respect to typical program control of a tokamak machine. This formulation determines the preprogramming voltages in the poloidal coil power supplies which are necessary for control of plasma current, posi-tion and cross section. The plasma dynamics used are described by a tokamak circuit model consisting of circuit equations for the plasma current and poloidal field coil currents, and equilibrium equations for the plasma position and cross section. The program control method presents the ideal preprogramming voltages which realize desired values for the controlled variables, when coil voltages are not restricted. This method is also applicable to problems where restrictions are imposed on the coil voltages.

By the thermal processing of the metals we can achieve the principal changes of their microstructure and likewise also principal changes of their mechanical and physical properties. When choosing a suitable heat processing for a specific application we rise from the required properties and knowledge about structural changes which are in the progress in the thermal changes. The solution of the speed up problem and increase heating quality of the metals belongs to the basic development trends of the thermal technique in the all industrial advanced states. The choice of the suitable mode of the metals heating is the problem that we also have in the steel coil annealing. In this paper is described program control of the steel coil annealing. The task of the program control is to ensure required behavior of the inner indirect measured temperature obtained from the system of the indirect measurement during which time control process variable is directly measured atmosphere temperature. Presented method rises from analyze of existence dependencies between atmosphere temperature and temperature inside the coil. The proposed control algorithm was verified with utilization of the simulation model for annealing process of the steel coils which is based on the system of indirect measurement of the inner temperatures.

Evolutionary algorithms for solving the problem of the optimal program control are considered. The most popular evolutionary algorithms, the genetic algorithm (GA), the differential evolution (DE) algorithm, the particle swarm optimization (PSO), the bat-inspired algorithm (BIA), the bees algorithm (BA), and the grey wolf optimizer (GWO) algorithm are described. An experimental analysis of these algorithms and their comparison with gradient methods are given. An experiment was carried out to solve the problem of the optimal control of a mobile robot with phase constraints. Indicators of the best objective functional value, the average value for several startups, and the standard deviation were used to compare the algorithms.

For a nonlinear controlled system, a fixed-time approach problem is considered in which the target point location becomes known only at the start of motion. According to the proposed solution method, node resolving program controls corresponding to a finite collection of target points from the set of their admissible locations are computed in advance and a refined control for the target point given at the start of motion is determined via linear interpolation of the node controls. The procedure for designing such a resolving control is formulated in the form of two algorithms, one of which is run before the start of the motion, and the other is executed in real time while the system is moving. The error in the transfer of the system's state to the target point by applying these algorithms is estimated. As an example, we consider the approach problem for a modified Dubins car model and a target point about which only a compact set of its admissible locations is known before the start of motion.

A computational technology involves the combined using of evolutionary finite-dimensional and infinite-dimensional multi-criteria optimization algorithms. A computational technology involves the combined using of evolutionary finite-dimensional and infinite-dimensional multicriteria optimization algorithms. Finite-dimensional multi-criteria optimization evolutionary algorithms are used to construct a discrete approximation of epsilon-effective solutions set. Infinite-dimensional multicriteria optimization evolutionary algorithms implement the stage of clarifying search, represent generalization of possible directions methods and use epsilon-effective solutions as initial approximations.
