A modified structure of the proportional-integral resonant controller and the method of adjusting its parameters are considered. It is shown that application of time-scale separation method makes it possible to perform calculation of proportional-integral component of controller independently from selection of parameters of resonant components of controller. The proposed approach to calculation of controller parameters allows providing almost perfect tracking for the given harmonic action in the control system under conditions of external harmonic disturbances and incomplete information on parameters of the control plant. The results of numerical simulation are given.

INTERNATIONAL JOURNAL OF HYDROGEN ENERGY 2024年 86卷 742-750页

作者： Vavilov, O. A. Yurkevich, V. D. Korobkov, D. V. Novosibirsk State Tech Univ Novosibirsk Russia

This paper examines the problem of synthesizing a two-loop control system for a three-phase voltage source inverter designed for an autonomous power supply system. This type of DC/AC converters is an essential part of power supply systems with renewable energy sources as primary sources, and, accordingly, must corresponds to the requirements for the electric power quality. These requirements are met through circuit design solutions, as well as through the construction of high-precision automatic control systems. The system integrates: a hydrogen electrolyzer, a hydrogen storage system, and a hydrogen fuel cell. The paper proposes a method for calculating the parameters of PI controllers with resonant components, based on the time-scale separation method and allowing independent adjustment of the controller components. The introduction of a resonant component ensures high tracking accuracy for a desired main voltage harmonic and selective suppression of external harmonic influences. The proposed approach allows to synthesize an automatic control system that significantly improves the quality of the voltage inverter output parameters.

OPTOELECTRONICS INSTRUMENTATION AND DATA PROCESSING 2022年第4期58卷 381-390页

作者： Yurkevich, V. D. Novosibirsk State Tech Univ Novosibirsk 630073 Russia

The problem of improving the synchronization accuracy of three-phase voltages of an autonomous four-wire inverter with the network is considered. Increasing the synchronization accuracy is achieved by applying a proportional-integral-differential (PID) resonant controller. A new structure of the PID resonant controller and a methodology for calculating its parameters are proposed. The peculiarity of the proposed approach consists in the application of the time-scale separation method, which makes it possible to calculate the PID component of the controller regardless of the choice of the parameters of its resonant components. Application of this approach to the calculation of the controller of autonomous voltage inverters makes it possible to improve electromagnetic compatibility and reduce losses in distributed power generation systems. The results of numerical simulation are presented.

This paper describes the problem of automation of parameter selection of an electrohy-draulic drive for a single-channel testbed for the strength load of aviation elements. It is proposed to tune the proportional-integral controller parameters of the testbed on the basis of the results of the tests based on relay feedback and time-scale separation method. The results obtained allow for autotuning the strength testbed controller parameters and increasing the accuracy of the strength load cyclograms, which eventually accelerates the strength tests. The results of applying this method on the experimental testbed are given.

The problem of control system design for a strength testbed of aircraft structures is considered. A method for calculating the parameters of a proportional-integral controller (control algorithm) using the time-scale separation method for the testbed taking into account the dead time effect in the control loop is presented. An adaptive control algorithm structure is proposed which limits the amplitude of high-frequency oscillations in the control system with a change in the direction of motion of the rod of the hydraulic cylinders and provides the desired accuracy and quality of transients at all stages of structural loading history. The results of tests of the developed control system with the adaptive control algorithm on an experimental strength testbed for aircraft structures are given.

Multi-channel Control System Design for a Robot Manipulator Based on the time-scale method

OPTOELECTRONICS INSTRUMENTATION AND DATA PROCESSING 2016年第2期52卷 196-202页

作者： Yurkevich, V. D. Novosibirsk State Tech Univ Pr Karla Marksa 20 Novosibirsk 630073 Russia

The problem of controller design for nonlinear multi-channel dynamical plants is discussed. Trajectory motion tracking control for a multilink manipulator is treated as an example of the proposed design methodology. A distinctive feature of the discussed approach to calculate controller parameters is that two-time-scale motions are artificially forced in a closed-loop system where stability of the fast mode is provided by selection of the controller parameters while the induced slow mode correspond to the reference model of desired nonlinear plant behavior. Simulation results for a two-link manipulator robot manipulator tracking control system are presented..

An anti-sway tracking control system for an overhead crane is discussed. The control objective is the sway-free horizontal displacement of the crane's load from one to other position. Based on the nonlinear mathematical model and singular perturbation technique the cascaded control system is designed which consists of two feedback loops. In the first control loop the sway angle proportional-integral-derivative (PID) control is provided by means of the force applied to the trolley in the horizontal direction. In the second one the horizontal movement of the trolley is regulated by the tracking PID controller in accordance with the desired velocity profile. Control system design procedure based on singular perturbation technique (time-scale separation method) is highlighted. Numerical simulation results are provided.

Problem of anti-sway tracking control for an overhead crane is treated based on a pendulum-trolley system. The control system is designed in order to provide the sway free horizontal displacement of a crane's load. The proposed control system consists of two feedback loops where in the first control loop the sway angle proportional-integral-derivative (PID) control is provided by means of the force applied to the trolley in the horizontal direction. In the second one the horizontal movement of the trolley is governed by the tracking PID controller in accordance with the desired velocity profile. Singular perturbation technique (time-scale separation method) is used for control system design. The effect of the velocity profile variation on the closed-loop system behavior is investigated. Numerical simulation results are presented.
