Transmit/Receive (T/R) modules plays important role in advanced phased array radar system consists of array of antenna elements. In order to produce beam pattern for multiple radiating elements, the phase angle for each T/R module should be assigned with calculated value. When phase gradient is sent to T/R unit, phase values are calculated for array of elements associated with them. The paper presents a beam steering control system architecture consists of Graphical user interface, group controller with scalable T/R control unit (TRCU) having two hexa decagon T/R module controllers (HTRMCs) and control logic unit for parallel data flow. Calculation of 6 bit phase value from the phase gradient carried out using FPGA. Also, use of logic core and quantization of phase values are discussed. The paper also reports the area factor for the proposed architecture

Area Efficient

Phased array radar architecture consists of the multiple antenna elements that are controlled by the active electronic circuits called T/R modules. Transmit/Receive modules (T/R modules) plays vital role in the modern phased array radar system for different radar applications. The problem asserted with electrically scanned phased array radar suffers from two main limitations. First one is the high hardware cost in terms of area and second one is the design complexity. To overcome the above issues, architecture has been developed by implementing single control unit, distributive memory elements and data control logic to design an area efficient control system. The entire system is implemented on Artix-7 FPGA.

The authors have offered the homeostatic control system architecture for digital manufacture security based on the software-defined network technology. We have highlighted the development features of digital manufacture systems and defined the technology advantages of software- defined networks, which allow these networks to be successfully applied with flexible and adaptive topology for a highly efficient new generation of cyber-physical systems. We have also described the main operating principles of software-defined networks in digital manufacture systems. A description of homeostatic security control technology, which includes a combination of engines to provide stability of the system’s internal environment and structural and functional resistance to external disturbances, is provided. We have proposed and described in detail the homeostatic security control system architecture including three generalized components: monitoring unit, decision-making unit, protection and control unit.

Measurement And Control

This paper presents the composition and working principle of the hardware and software of the measurement and control system based on VeriStand and Simulink for a tracked model vehicle. The hardware of the system is composed of a CompactRIO controller and acquisition cards, torque/speed sensors and a gyroscope. The vehicle control logic model and data processing model are built in Matlab/Simulink. VeriStand is adopted to manage models and interact with people. The system can control motor speed on both sides of the vehicle and collect data such as sprocket torque and speed, vehicle attitude on real-time. At last, we test and verify the system can work successfully.

Modular approach has been adopted in this paper to divide DCT transmission control unit into four modules, which are clutch control, synchronizer control, shift assembly control and vehicle control respectively. The function for each module has been analyzed and the control logic relations among these modules have also been established for modular integration. Moreover, the modeling process and control strategies for each module have been established for respective control objection. On this basis, the simulation model of transmission control unit for DCT has been built using the Matlab/Simulink platform, and the simulation has been carried out at given throttle opening. The results show that the control strategy of transmission control unit for DCT has been validated, which provides theoretical basis for DCT product development.
