Item type:Article, Access status: Open Access , Kronika i informacje(Wydawnictwa AGH, 2016) Mitkowski, WojciechItem type:Article, Access status: Open Access , Modelling of Unmanned Aerial Vehicle - Tricopter(Wydawnictwa AGH, 2016) Źrebiec, JakubThis paper presents detailed models of small aerial unmanned vehicle's subsystems like propeller, BLDC motor or Li–poly batery. Furthermore, more accurate dynamic model of Tricopter is described. This, multi–system model can be used to synthesize pecise controller which may have the advantage in hazardous situations.Item type:Article, Access status: Open Access , Kronika i informacje(Wydawnictwa AGH, 2016) Mitkowski, WojciechItem type:Article, Access status: Open Access , On D-decomposition of periodically sampled systems(Wydawnictwa AGH, 2017) Jańczak, JustynaThe problem of the stability of non-uniformly sampled systems is considered. For this purpose, the D-decomposition method for determining the stability region in parameter space is investigated. Moreover, basic information about non-uniform sampling are presented, with an emphasis on periodic sampling. Based on the obtained simulation results, some comparisons of systems with different sampling patterns are considered.Item type:Article, Access status: Open Access , Supervising control system for oriented PV using weather forecasts(Wydawnictwa AGH, 2017) Ciurej, MaciejThis paper is devoted to the problem of controlling an oriented PV using weather forecasts. The described solution presents the use of fuzzy logic fundamentals in order to increase the efficiency of a PV system. It differs from most related papers in the fact that it uses fuzzy logic in order to process weather condition numeric values as input data. All of necessary steps to reproduce the proposed solution have been included.Item type:Article, Access status: Open Access , The use of EMG signal in human-machine interface(Wydawnictwa AGH, 2015) Winiarski, DawidIn this paper, the analysis and processing algorithms of EMG signals have been presented. The main purpose of the research was to verify the usefulness of EMG signals in controlling a bionic prosthesis or exoskeleton. The physiological nature of the EMG signal has been introduced. An original measurement system has been presented. Analysis of the time and frequency domains of the signal has been conducted to extract vital information that the signal carries. Methods of using the EMG signal as a control signal for devices that operate in a human-machine interface have been proposed. The result shows that a processed EMG signal can be used as a basis for a simple control system.Item type:Article, Access status: Open Access , Online environment for data acquisition from car sensors(Wydawnictwa AGH, 2019) Kowalik, Bartosz; Szpyrka, MarcinModern cars are equipped with plenty of electronic devices called electronic control units (ECUs). They collect diagnostic data from a car’s components to control their work, assess the quality of their work, and detect defects. Regardless of the development of onboard computers, only a small amount of information is passed on to the driver. This paper describes how to build a data-collecting environment for real-data acquisition from a car. The system (whose components include an Android- -based smartphone and Torque PRO application) is able to send data via the Internet to a chosen server in real time. The collected data can be further analyzed both online and offline.Item type:Article, Access status: Open Access , Wspomnienie o doktorze inżynierze Piotrze Tabakowskim(Wydawnictwa AGH, 2015) Turnau, AndrzejItem type:Article, Access status: Open Access , Novel method to simplify Boolean functions(Wydawnictwa AGH, 2018) Prasad, V. C.Most methods for determining the prime implicants of a Boolean function depend on the minterms of the function. Deviating from this philosophy, this paper presents a method that dependson maxterms (the minterms of the complement of the function) for this purpose. Normally, maxterms are used to get prime implicates and not prime implicants. It is shown that all prime implicants of a Boolean function can be obtained by expanding and simplifying any product of sums form of the function appropriately. No special form of the product of the sums is required. What is more, prime implicants can generally be generated from any form of the function by converting it into a POS using well-known techniques. The prime implicants of a product of Boolean functions can be obtained from the prime implicants of individual Boolean functions. This allows us to handle big functions by breaking them into the products of smaller functions. A simple method is presented to obtain one minimal set of prime implicants from all prime implicants without using minterms. Similar statements also hold for prime implicates. In particular, all prime implicates can be obtained from any sum of a products form.Twelve variable examples are solved to illustrate the methods.Item type:Article, Access status: Open Access , Design, construction and control of a spherical rolling robot with internal two-wheel cart(Wydawnictwa AGH, 2015) Firlej, SzymonThis elaboration presents a spherical rolling robot with a 2-wheel cart. The custom design of the hardware and control software is presented to demonstrate the solution. The robot was started to realize an autonomous task. The embedded robot control system is based on a 32-bit microcontroller and uses a Bluetooth module for wireless communication. The simplified model has been proposed and its parameters identified. The results obtained at the simulation and experimental stages are shown and compared. Finally, the robot’s motion was recorded and analyzed with the support of image signal processing techniques.
