While model predictive control (MPC) is the industrially preferred method for advanced control in the process industries, it has not found much use in consumer products and safety-critical embedded systems applications in industries such as automotive, aerospace, medical, and robotics. The main barriers are implementability and dependability, where important factors are implementation of advanced...
The remarkable growth of the different applications for unmanned aerial vehicles (UAVs) are currently of high research interest. This paper proposes a new approach for the attitude control system of a fixed wing aircraft. Using techniques of Artificial Intelligence (AI), this research presents a solution that uses Adaptive Neuro-Fuzzy Inference System (ANFIS) as flight dynamics identifier, and genetic...
As RF environments become more complex from both targeted attacks and challenging RF propagation environments (e.g. urban), pre-planned placement of deployed communications elements becomes arduous for the network planner supporting the digital battlefield. We propose a novel dynamic range extension approach that builds upon our extant planning and optimisation tool, HARLEQUIN, to automatically and...
Software-defined network (SDN) is deemed to enable more dynamic management of data center networks that promptly respond to network events with changes in network policies. Although the SDN controller architecture is increasingly optimized for swift policy updates, the data plane, especially the prevailing TCAM-based flow tables on physical SDN switches, remains unoptimized for fast rule updates,...
SDN research is moving towards enabling the delegation of parts of control functions to the network elements. In recent work we analytically evaluated the benefit in terms of ARP data traffic load reduction as well as control channel interaction reduction when delegating the generation of ARP replies. In this paper we describe the corresponding control program and network configuration to handle ARP...
Building management system is used to control and monitor electrical and mechanical systems in modern buildings. In the current world there are various solutions for large scale building management and the trend is to integrate all of them together to have more reliable and convenience system. When we come to the point of moderate scale buildings, there are electrical services systems such as CCTV,...
This paper presents a solution to the sampled-data H2 control problem where the sampling function, the discrete-time controller and the hold function are all available for design. In contrast to previous works, the generalized sampling and hold functions are constrained to have piece-wise impulse and piecewise constant waveforms, respectively. The resulting sampling and hold devices improve the control...
The traffic demand in wireless access networks has grown substantially in recent years and is expected to continue doing so, both in terms of total volume and data rate required by individual users. To overcome the current limitations of wireless access networks, operators already push for very dense and heterogeneous wireless networks, commonly known as DenseNets. Efficiently controlling DenseNets...
According to parameters adjustment problems of fractional order PID controller applied in time-varying, nonlinear, real-time demanding higher systems, an improved particle swarm optimization (PSO) algorithm is adopted to optimize fractional order PID controller parameters. Because of high complexity of PSO and long tuning time, the paper adopts FPGA and combined with external circuit to implement...
Fuzzy logic based control systems provide a simple and efficient method to control highly complex and imprecise systems. However, the lack of a simple hardware design that is capable of modifying the fuzzy controller's parameters to adapt for any changes in the operation environment, or behavior of the plant system limits the applicability of fuzzy based control systems in the automotive and industrial...
Itpsilas well known that parametric fuzzy conjunction and disjunction operations have not effective hardware implementation because they use product and computing powers of operations in their definitions. New approach of generation of non-associative conjunctions fuzzy operations has been developed. Based on this new method parametric classes of fuzzy operations, suitable for effective hardware implementation,...
Synthesis of finite state machines (FSM) with transformation of the object's codes is given. The general method of transformation of codes of state in the codes of microoperations' sets and vice versa is proposed. The circuit structures of Mealy and Moore automata are proposed and the method of their design is discussed. The further optimization is connected with increasing the circuit's levels. The...
