PID Neural Network Control System of Multi-variable and Strong-coupled Time-varying System
SHU Huai-lin , GUO Xiu-cai
2003, 29(5): 16-18.
<Abstract>(35)
Abstract:
The paper introduced a new kind of neural network: PID neural network and its multi variable and strong coupled time varying system. The structure and the algorithm were given, the characteritics of the time varying system were analyzed, the real time simulation results of double variable and strong coupled time varying system were shown. It proved that the PID neural network has perfect decouple and self learning control performance for strong coupled time varying system.
Study on Oxygen Gas Sensor Used in Auto’s Motor
MA Yu-fang, LU Shi-kui
2003, 29(5): 19-20.
<Abstract>(32)
Abstract:
The motor’s tail gas must be handled by trinity catalyst before it exhausts and the rate of purification is related to the content of the oxygen. At the same time, matching to the economization, we can realize the real time control of the proportion of air and fuel by mensurating the content of oxygen, and insure that the fuel in cylinder burns well. In this way, the harmful gas is reduced, so the oxygen gas sensor is needed. This paper described the development condition on ZrO2 gas sensors, and introduced the sensor’s structure, working principle and applications. Key technology, such as new extender’s appending are also discussed.
