Measurement And Control

This paper will give a solution of measurement and control system based on FPGA embedded system for the Plastic Material Dynamic High-speed Tensile Machine (PMDHTM) with 1-100s-1strain rate range. Using sub-modules design of Nios II soft-wore and SOPC to build measurement and control system. The state machine algorithm and servo drive device are applied to accomplish precise state control of the linear shaft motor. Collecting the stress data online and non-contacting strain measurement is adopted. The test result can well meet the linear motor control response demand below the 5Hz frequency. Compared with other control based on SCM, DSP and so on, it supplies an innovation way for the PMDHTM control.

Impact Angle Constraint

An integrated guidance and control method is investigated for interceptors with impact angle constraint against a high-speed maneuvering target. Firstly, a new control-oriented model with impact angle constraint of the integrated guidance and control system is built in the pitch plane by combining the engagement kinematics and missile dynamics model between the interceptor and target. Secondly, the flight path angle of the target is estimated by extended Kalman filter in order to transform the terminal impact angle constraint into the terminal line-of-sight angle constraint. Thirdly, a nonlinear adaptive sliding mode control law of the integrated guidance and control system is designed in order to directly obtain the rudder deflection command, which eliminates time delay caused by the traditional backstepping control method. Then the Lyapunov stability theory is used to prove the stability of the whole closed-loop integrated guidance and control system. Finally, the simulation results confirm that the integrated guidance and control method proposed in this paper can effectively improve the interception performance of the interceptor to a high-speed maneuvering target.

Measurement And Control

In order to meet the high speed, high precision, high reliability of the packaging machine, a novel control system is provided. In the hardware, the main circuits consisted of main processor module, memory module, temperature measurement and control module, input signal detection module, material split packing module, output driver module, human-machine interface module, system monitor module, power module and JTAG debug module, etc. In the software, the multi-tasking operating system μC/OS-Ⅱ and the graphical user interface μC/GUI were successfully transplanted into LPC2478. Then an experimental platform was established. And many control tasks, including automatic measurement, making bags, loading, transferring, pumping vacuum, sealing and data display, were automatically and continuously executed on the platform. Finally the results show: the machine can package 30 packets (5 g per packet) in a minute; the packaging errors ≤ 0.2 g; the packaging qualified rates ≥ 93%. In conclusion, the system performance is good.
