In this paper, the possibility of using the virtual commissioning for developing the advanced controllers for example of electric flow heater is presented. First, based on the process measurement data, the virtual environment is prepared. Then, for selected advanced control algorithms, both virtual and real commissioning was carried out. The results are discussed in the paper and they demonstrate the impact of the applied commissioning method on the control performance provided by each of considered control algorithms.

In this paper, the nonlinear dynamics of the biological system modeled by the fractional incommensurate order Van der Pol equations are investigated. The stability of the proposed fractional non-autonomous system is analyzed by varying both the fractional order derivative and system parameters. Moreover, very interesting phenomena such as symmetry, multi-stability and coexistence of attractors are discovered in the considered biological system. Numerical simulations are performed by considering the Caputo fractional derivative and results are reported by means of bifurcation diagrams, computation of the largest Lyapunov exponent, phase portraits in 2D and 3D projections.

This paper develops iterative learning control laws for a subclass of uncertain spatially interconnected systems. Model uncertainties appear both in the state (represented by the norm bounded description) and the output equation (represented by a polytopic description) of the dynamics modeled in the 2D systems setting. A particular example of an RLC ladder circuit provides an example to motivate the analysis. The first stage is to write the dynamics in 2D model form and then to apply the stability theory for a distinct class of 2D systems known as repetitive processes is used to develop the ILC law in the case of differential dynamics. This results in a design algorithm that considers the mixed uncertainties in the model and can be applied using linear matrix inequalities.
In the paper we investigate an uncertain single machine total weighted tardiness problem where uncertainty of times of jobs execution and jobs deadlines are modeled by random variables with a normal distribution. We c...

This paper presents a comprehensive review of state-of-the-art occupancy grid mapping approaches for highway and urban automotive applications. The primary objective is to identify most suitable algorithm candidates for series applications. The occupancy grid functional performance requirements for automotive are given. A new high level grid fusion architecture is introduced. The innovative element is a second stage filtering step allowing better performance in case of highly uncertain inputs. An application of the architectures to an example sensor suite is proposed.

A permanent growth of forklifts' indoor practical applications such as high-storage warehouses makes them dominating transportation tools. It rises the need for their coordinated scheduling including uncertainties related to the human operator behaviour. To tackle this problem, in the paper a novel comprehensive fuzzy logic-based methodology enabling modeling cooperating forklifts and their robust fault-tolerant scheduling is proposed. The advantage of the developed methodology is that it can overcome inevitable conditions like faults, environmental or human-like disturbances and uncertainties. To settle this problem a fuzzy algebraic max plus algebra-based model is proposed and accompanied with a suitable predictive scheduling algorithm. Subsequently, the proposed approach is extended by fault diagnosis mechanisms resulting in a new centrally managed predictive fault-tolerant scheduling system. The efficiency of the proposed approach is evaluated using various simulation scenarios which involve cooperating forklifts transportation tasks operating in a high-storage warehouse of RAFI GmbH & Co. KG company.

In this paper we propose a flying IoT system designed to monitor parking lot. The system is composed of a flying mobile station and a terrestrial station. The mobile station consists of visual monitoring camera associated with air quality monitoring sensors, mounted on a Turnigy SK450 quad copter controlled with Pixhawk autopilot hardware. Data gathered from the monitoring system are transmitted to an IoT broker running on a Raspberry Pi 3+ microcontroller, also mounted on a drone, that aggregates data into a common flow and retransmits them to the terrestrial station. The transmission system was build according to WebRTC architecture. In order to assure separation of the production network (for transmission of application data) and the management network (for management and control purposes), two different transmission channels are used: one for the WebRTC transmission and the other for controlling the drone. The paper includes a description of the system and the results of field trials carried out on the parking lot of the AGH University of technology.
