The DC motor speed control is commonly used in several robotic applications. Thus the controller design for the DC motor speed control is a compulsory to optimize the performance of the motor towards the system design specification. In this paper the DC motor mathematical model is obtained then Three linear controllers, which are PID, LQR, and Q-parameterization controllers are designed for controlling the DC motor speed. The performance of the control techniques is compared in terms of transient response and steady state error performance. The comparison amongst the controller shows that the Q-parameterization controller significantly reduces the transient response performance and also steady state error. © 2012 IEEE.

In this tutorial some basic linear algebra problems: basis change and projection, are discussed together with examples of their applications in signal and image processing. In typical linear algebra university courses perpendicular projections are only discussed. However, in image processing, for defining various color spaces, we need non-perpendicular projections. That is why this is the key problem in this tutorial. © 2024 Division of Signal Processing and Electronic Systems, Poznan University of Technology (DSPES PUT).

Measuring luminous intensity using electronic sensors requires their precise positioning. In the case of mobile measurement platforms, it is important to detect the light source and thus determine the correct direction of movement of the measuring device. This article presents research on a solution for the initial detection of glowing airport lamps based on camera images. The impact of the selection of parameters and image processing methods on the prepared data set was assessed. The histogram filtration method was introduced to improve the effectiveness of airport lamp localization. The proposed solution was investigated in different weather and daytime conditions. The overall accuracy of the proposed solution is more than 90%. © 2024 Division of Signal Processing and Electronic Systems, Poznan University of Technology (DSPES PUT).

The latest EASA recommendations from 2024 indicate the possibility of using machine learning techniques in aerodrome monitoring. The aim of the work was to analyze solutions and prepare FOD (Foreign Object Debris) object detection software on aerodromes. In order to implement the issue, a dataset of photos and video recordings for testing algorithms was developed. The dataset consists of 1480 photos showing FOD at aerodromes and photos of the runway itself, according to EASA and FAA recommendations. FOD detection was implemented using a classical, k-means method and effective YOLOv5. © 2024 Division of Signal Processing and Electronic Systems, Poznan University of Technology (DSPES PUT).

In the paper the problem of modeling of thermal processes in microcontroller system is addressed. The proposed models allow to describe thermal processes during work of an evaluation system. The temperature in critical places of the system is measured using thermal camera. The proposed models have the form of hybrid transfer functions, containing both Integer Order (IO) and Fractional Order (FO) parts. The step responses of the proposed transfer functions are computed analytically. Results of experiments show that the proposed models are more accurate in the sense of Mean Square Error (MSE) cost function than typical transfer function models with delay. The proposed models can be applied to predict of overheating of microcotroller systems. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2023.

In the last decades, the renewables market is focused on distributed grids and solutions suitable for private use in households. A low-speed wind turbine based on the Magnus effect is one of the promising technologies in that area. By its construction, for the power management, Magnus effect-based wind turbine requires additional motors to control the rotational speed of the blades. An integrated motor-drive system for Unmanned Autonomous Vehicles (UAVs) matching the requirements in terms of weight, size, rotational speed, and controllability. In this case study, an application of the permanent magnet synchronous motor (PMSM) designed for UAVs in a Magnus effect-based wind turbine prototype is presented. The control system design methodology is presented, and the performance of the system is experimentally evaluated. © 2021 IEEE.

Switched reluctance motors (SRMs) are capable of operating at high speeds and high loads. However, the large back-EMF results in the excitation winding current being demagnetized more slowly, which in turn reduces the efficiency and output of the motor system. This study proposes a novel individually demagnetization power converter (IDPC) specifically designed for SRMs to effectively utilize the demagnetization energy through an independent demagnetization circuit. Compared with traditional converters, the IDPC can accept direct current (DC) and high-frequency alternating current (AC) inputs while achieving fast demagnetization and energy recovery. The topology and working principle of the IDPC are analyzed in detail in this paper using a three-phase 12/8 SRM as the research object. In addition, the influence of the winding demagnetization voltage on the negative torque during the demagnetization phase was studied, as well as the functional implementation and logic control strategy of the IDPC. Simulation and experimental results confirm the validity of the proposed topology and high-frequency AC drive characteristics, as well as their advantages in terms of efficiency, output capacity and dynamic performance. © 2015 IEEE.

In the paper the numerical estimation of the internal positivity of the model of a two dimensional heat transfer process is addressed. The considered thermal process is described by the fractional order state equation, derived from parabolic heat equation with homogenous Neumann boundary conditions and distributed control and observation. Two numerical algorithms of the positivity testing are proposed and compared. The first one consists in the full examination of the whole area. The next one uses Monte Carlo method. From tests it can be concluded that the considered model can be internally positive only for its lower orders and heating and measurements located closely to the corner of the tested area. The use of the Monte Carlo method allows to significantly shorten the duration of computations. The presented results can be useful in measurements using a thermal camera. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.

This paper presents two robust optimal controllers for Cooperative Manipulators (CoMans) holding an object on the basis of a modified factorization approach. Due to advantages such as: simplicity, flexibility, systematic procedure and not canceling nonlinearities, the State-Dependent Riccati Equation (SDRE) has been chosen as a basis for robust controllers design in the literature. For developing robust optimal controllers via SDRE, the first step is to obtain uncertain State-Dependent Coefficient (SDC) representation. To design robust optimal schemes for some systems such as CoMans, some terms such as gravity, friction and the external forces have been neglected in the uncertain SDC structure and added to the control input. This study, proposes two robust optimal controllers for CoMans carrying a load: Mixing SDRE-SMC (MiSS) and transformed robust to optimal controller where the pre-mentioned terms can be included in the uncertain SDC representation called uncertain optimal SDC. Simulation results are provided to easily verify the satisfactory performance of both schemes using uncertain optimal SDC and superiority of the transformed robust to optimal control versus MiSS in trajectory tracking of CoMans. © 2022 IEEE.
