The increased need for accurately modeling the input-output characteristics of linear time-periodic (LTP) systems necessitates novel identification and control algorithms as well as new test benches for their experimental validation. This paper introduces a simple-to-build test bench for the identification and control of LTP systems. We mechanically coupled the shafts of two DC motors and fed back the angular velocity to the second motor with a time-periodic modulation. This allowed us to imitate a time-periodic load for the first DC motor, thereby yielding an experimental LTP plant. We used Matlab/Simulink target hardware support to implement the entire software in Simulink, which greatly simplifies input design, data collection, and analysis as compared to embedded programming. We used constant-frequency sinusoidal signals for the data collection on the experimental test bench. Subsequently, we estimated the harmonic transfer functions and identified the parameters of a state-space model of the proposed LTP system. We then designed a time-periodic controller in order to regulate the output of the LTP system. We designed a reference-tracking controller along with a Linear Quadratic Integrator (LQI) to improve the system performance. We validated our results through experiments on the physical LTP system plant. © 2023 IEEE.

The share of renewable energy sources in the energy mix worldwide is gradually increasing. And even though they all have a highly variable nature, they can be forecasted statistically. The wind energy potential was investigated in this article in the Bulgarian Danube region, located between Ruse and Silistra. Two years of meteorological data, including the wind speed at 10 m height and the ambient temperature was used to estimate the average wind energy for each month of the year at three geographic locations - Ruse, Staro Selo (near Tutrakan), and Calarasi, Romania (near Silistra). The results showed that Staro Selo has the highest energy potential, reaching up to 0.75 kWh/day/m2 in February, followed by Calarasi with 0.38 kWh/day/m2. The city of Ruse showed the lowest wind potential with the highest average monthly value reaching only 0.0027 kWh/day/m2. The obtained results showed that the regions around Tutrakan and Silistra are appropriate for the application of micro wind turbines. © 2024 IEEE.

The diverse requirements of customers in automation systems increase the need for improved adaptability, flexibility and of simplicity production processes. which creates new horizons for modern production systems. Fortunately, the achievements of the Industry 4.0 (fourth industrial revolution) have provided many solutions to these problems. In this study, an OPC UA-based solution is proposed for monitoring the working process of CAN servo drives. By integrating C++ based OPC UA libraries to implement common OPC UA functionality and developing protocol of interaction between the kernel of CNC system and OPC UA server. The aim of this work is to ensure the connection mechanism between OPC UA Server of CNC system and OPC UA clients which are currently existed on the market. This flexible model allows users to remotely tune and set up CAN servo drives and monitor their work.

Active Fault Diagnosis in Sampled-data systems

IFAC-PapersOnLine 2015年第21期48卷 883-888页

The focus in this paper is on active fault diagnosis (AFD) in closed-loop sampleddata systems. Applying the same AFD architecture as for continuous-time systems does not directly result in the same set of closed-loop matrix transfer functions. For continuous-time systems, the LFT (linear fractional transformation) structure in the connection between the parametric faults and the matrix transfer function (also known as the fault signature matrix) applied for AFD is not directly preserved for sampled-data system. As a consequence of this, the AFD methods cannot directly be applied for sampled-data systems. Two methods are considered in this paper to handle the fault signature matrix for sampled-data systems such that standard AFD methods can be applied. The first method is based on a discretization of the system such that the LFT structure is preserved resulting in the same LFT structure in the fault signature matrix as obtained for continuous-time systems. The other method is an approximation method, where the same structure is obtained for small parametric faults. © 2015

The article presents a simulation model of a pneumatic drive for electrodes of a stationary contact spot welding machine. Thanks to the developed model, it becomes possible to analyze the system, as well as visually study its operation. The result of modeling the system is the obtained transients of the elements of the pneumatic system. The developed simulation model adequately describes the state and behavior of a real system of pneumatic compression of electrodes. The work is of interest to pneumatic engineers, designers and other specialists working in the field of pneumatics and can be used for more accurate and efficient design, analysis and optimization of not only a specific system of pneumatic compression of electrodes, but also pneumatic systems in general. © 2023 IEEE.
