Through the analysis of RTLinux source code and real-time performance of various testing experiment on the RTLinux, and its application in a distributed robot control system using CAN bus, realize the real-time control of robot joints. Write the code of real-time module on RTLinux, analyzing the real-time performance using related kernel time testing function. Under Linux using QT write user interface for robot control, running on the Linux user space. The interface program and the real-time program communicate via RT-FIFO. Specify the location of each robot joint in the interface program, compared with the feedback from the actual joint position trajectory, evaluate the control effect of real-time systems.

Memristor Crossbar

Fuzzy control, an intelligent control method, is generally employed to deal with complex nonlinear controlled objects that cannot be expressed by accurate mathematical model. Memristor, whose unique advantages are automatic successive memory and nonvolatility, brought new opportunity for solving the key question of fuzzy control. With the design idea of software harden, this paper first constructed membership function in the fuzzy controller based on the unique feature of crossbar array of the spintronic memristor and elaborated the whole construction process. After that, this paper simulated the construction process with MATLAB simulation software, verifying its reasonability and feasibility. Furthermore, a typical fuzzy control water tank system was chosen to explore and discuss the flexibility of spintronic memristor crossbar array in the real-time control system, and the proposed control strategy and the typical fuzzy control strategy were compared. The results revealed that the proposed control strategy was able to attain the effectiveness of the typical fuzzy control system in the real-time control system. This sets light to future research on the implementation of memristor crossbar array in the real-time control system and also promotes the application of fuzzy controller design idea. The problems needed to be solved when implementing memristor crossbar array in the real-time control system were discussed in the final section.
