This paper presents models of economic growth for all states of the European Union (EU), since either 1970 or the year of accession to the EU. Both integer and fractional order models are obtained, where the gross domestic product (GDP) is a function of the country’s land area, gross capital formation (GCF), exports of goods and services, and average years of school attendance.
In this paper, the problem of crossing the inter-sections is studied. A controller is designed based on a hybrid automaton. The design procedure is presented into two cases. The problem of crossing with one automatic car and one manual car from intersection is studied in case one. The safe crossing (i.e. fixing safe distance between two automatic car)of two automatic cars is studied in case two. Simulation...
This paper deals with the implementation of an auto-tuning method for fractional order PIλDμ controllers using a PLC. The purpose of the auto-tuning method proposed is to ensure a robust performance of the controlled system with respect to plant gain variations. Specifications of gain crossover frequency and phase margin are fulfilled, together with the iso-damping property of the time response of...
The performance of a networked control system (NCS) is affected directly and indirectly by transmission time delays and data losses in the communications network. Based on the communications network model, this paper presents the validity of two different predictive control strategies and the study of the network effects on the lateral (guidance) control of an autonomous guided vehicle (AGV) in the...
The performance of an networked control system (NCS) is affected directly and indirectly by transmission time delays and data losses in the communications network. This paper presents the modelling of main problems of a communications network in an NCS, and the study of their effects on the longitudinal (velocity) and lateral (guidance) control of an autonomous guide vehicle (AGV). The results are...
The performance of a networked control system (NCS) is affected directly and indirectly by transmission time delays and data losses in the communications network. Based on the communications network model, this paper presents two different control strategies and the study of network effects on the lateral (guidance) control of an autonomous guided vehicle (AGV) in the presence of sensor noise: bounded...
