Clutch Control

The paper presents description of a mechatronic control system for mechanical transmission of a 20-ton truck, as well as its adaptive start-up algorithm, transient process behavior which significantly affects durability of automated power unit elements, vehicle movement smoothness and driver’s comfort when driving. A multidisciplinary model of the mechatronic control system has been developed in the software package Imagine Lab AMESim because its power unit including a diesel engine, a dry frictional two-disc clutch, a main mechanical stepped gearbox and an additional gearbox has electrical components besides mechanical and pneumatic ones. The given model allows to test complex control algorithms and analyze the behavior of intelligent systems in the early designing stages. The research has been carried out on the basis of the test complex at Department “Automobiles”, Automotive and Tractor Faculty, Belarusian National Technical University. Research results confirm an adequacy of the AMESim developed multidisciplinary model. Feedback on the increment of an angular velocity difference between driving and driven parts of the friction clutch has been introduced for precise friction clutch control. Threshold values of a feedback parameter have been determined on the basis of the developed computer model and these values will be used for programming a microprocessor unit when implementing an adaptive algorithm for a truck start-up process

The dynamic development of the construction industry in Russia is accompanied by an increase in the complexity of ongoing projects and, as a result, an increase in the flow of information processed. It is necessary to manage a large number of different in intensity, direction, volume, flow patterns of informational, material and technical flows, as well as the flow of regulatory influences. In this regard, it is advisable to use a multi-level approach to planning the implementation of investment and construction projects in order to increase the efficiency and intensification of the construction industry. The article deals with the problem of regulation of phenomena and processes occurring in the space of investment and construction activities, by economic methods towards the realization of sustainable development goals. Options for the implementation of integrated control based on the investment program engineering control scheme are proposed, a flowchart of the algorithm for linking and implementing strategic controlling and operational management procedures within the framework of the integral control of construction projects of technically complex and unique objects is formed.

Proportional Integral Control

A novel control scheme for the dynamic voltage restorer (DVR) is proposed to achieve fast response and effective sag and swell compensation capabilities. In this control scheme, the proportional integral control is used to guarantee system dynamic performance and the repetitive control is used to improve voltage waveform quality. Compared to classical proportional integral control, DVR based on this control scheme can restore load voltage almost sinusoidal and shows better transient and steady-state responses when facing sag or swell conditions. The proposed control scheme has been verified by simulation on Matlab. Simulation results show that the control approach performs very effectively and yields excellent voltage regulation.

Proportional Integral Control

Wind energy is regarded as one of the oldest energy sources and has played a significant role. As the nature of wind changes continuously, the generated power varies accordingly. Generation of the pitch angle of a wind turbine’s blades is controlled to prevent damage during high wind speed. This paper presents the development and application of a fuzzy proportional integral control scheme combined with traditional proportional control in the dynamic behavior of pitch angle-regulated wind turbine blades. The combined control regulates rotor speed and output power, allowing control of the power while maintaining the desired rotor speed and avoiding equipment overloads. The studied model is a large-scale wind farm of 120 MW in the Gulf El-Zayt region, Red Sea, Egypt. The control system validity is substantiated by studying different cases of wind speed function: ramp, step, random, and extreme wind speed. The results are compared with the traditional combined control. The model is simulated using MATLAB/SIMULINK software. The simulation results proved the effectiveness of fuzzy tuned PI against traditional PI control.
