The article addresses specific issues of the automated heating systems for non-residential buildings, which aim to ensure thermal comfort with low energy consumption. The specialized automatic system maintains constant the indoor temperature when the heat input in building equals the heat loss through the building envelope. The specialized automatic system consists of several subsystems. The model...
A novel pressure control system based on a centrifugal pump Simulink model is proposed aiming to reduce energy consumption during pump operation. The system developed provides the possibility of power reduction during pressure maintenance with the help of mixed pressure control strategy. To evaluate the system, a series of tests have been conducted that proved that the designed system is more beneficial...
In this paper, the simulation environment is proposed that enables accurate full-scale investigation of the pressure adjustment for a centrifugal pump. The novel Matlab model is described, the pumping control procedure is explained, and the simulation results are assessed with the help of an experimental pumping test bench. Basing on thorough inspection of the developed software, the offered toolbox...
Interaction between humans and robots is expected to increase in the coming years. In order to ensure safety for the robot, its environment, and the people around it, it is necessary to have robust compliance actuation. Mechanically compliant devices such as magnetorheological actuators can ensure a high degree of safety through their intrinsic properties. This paper presents the modelling of a new...
The proposed paper deals with the problem of modelling and simulation of a dual-redundancy Electro-Hydrostatic Actuator (DREHA) by the way of co-simulation based on AMESim and MATLAB. With the development of More Electric Aircraft (MEA) technology, integrated Power-by-Wire (PBW) actuator will be used in the airborne actuation system. As an important PBW actuation system, EHA has virtues of high efficiency,...
This paper shows control results of simulations on mathematical model and real measurements on the real model of the water tank. The level in the tank is controlled via input volumetric flow rate through the proportional solenoid valve. The adaptive approach with the recursive identification was employed here for controlling of this system. The controller could be tuned by the choice of the pole position...
Traditional control design techniques like manual tuning are widely employed within the Continuously Variable Transmission (CVT) industry. However, manual tuning comprises of trial and error and is therefore time consuming. Moreover, the results are likely far from optimal in the sense of some predetermined set of criteria for ratio tracking performance and control effort. For such a complex dynamic...
Due to the ignorance of the instability of hydraulic cartridge sequence valve and the resulting accidents, this paper presents stability analysis of the cartridge sequence valve. First, the operation of the valve was illustrated, then a theoretical analysis was given, and simulation under AMESim environment was carried out, hence the variations of the control variables during the dynamic process were...
