Due to the increasing flexibility and the mobility, wireless security communication in the industrial control field is a challenging. In this paper, we propose one approach of security mutual authentication scheme with key agreement for WIA-PA networks, which is significant to security provisioning in industry wireless network with resource limitations. Then we implements the new node security join the network and communication to enhance the capacity of preventing the attacks. Based upon the provision concept, the proposed scheme does not require public keys for users such that the additional computations for certificates can be reduced. Finally, our test results show these security methods may be used in the field environment to realize the security reliability of the wireless industrial network communication. Copyright 2011 ACM.

In order to improve the control effect of the Superheater Steam Temperature(SST) for a 300 MW boiler unit, this paper presents an inverse compensation control scheme based on the expanded-structure neural network inverse modelsThe input and output variables of the expanded–structure neural network Inverse Dynamic Process Models(IDPMs)for the superheater system are determined from understanding of the boiler operating characteristicsThen, two neural network(NN) inverse controllers are designed with the IDPMs as on-line output compensators for the original cascade PID controllers in order to improve the control effectDetailed simulation tests are carried out on the full-scope simulator of the given 300 MW power unitIt is shown by tests that the control effects of the NN-compensated control on the SST are significantly improved compared with the case of the original cascade PID control scheme.

In this article we present a mathematical model of a spincopter -an inherently stable and easy to control unmanned aerial vehicle (UAV). Although the devised model represents only the first approximation of spincopter's physics, it captures basic phenomena that are sufficient for derivation and testing of a simple control algorithm. Results obtained by simulations in Simulink presented herein, demonstrate efficient performance of the proposed simple controller structure. Further tests, including investigation of complex aerodynamics effects and hardware-specified limitations, have been done using X-Plan software package. Finally, the proposed controller has been tested experimentally. Both, Xplane and experimental results confirmed the outcome from Simulink.
