Abstract-For the disadvantages of being easy to fall into premature of particle swarm optimization and the lengthy process of immune algorithm, putting the immunization information processing mechanisms of the immune system into PSO algorithm. A particle swarm algorithm based on immune selection (IPSO) was proposed, and its application to the parameter tuning and self-adaption in PID controllers, and designing the PID controller parameters. Simulating by MATLAB, experimental results showed that the algorithm can solve the problem of PSO algorithm premature convergence, and applying to self-tuning PID controller.

Abstract-For realizing the network and information of highend printing machines, the remote fault monitoring system based on Apache, MySQL and PHP under the Windows system (WAMP) for network environment is presented. The open source environment of WAMP is used in this system, which can easily set up a remote site and realize the network system of the b/s structure, and is convenient for secondary development. Designing a data transfer interface based on TCP/IP protocol that allows the clients to transfer the field device data to the site server and store in the local database, which is also used to display the current status, publish historical data and diagnose the remote troubleshooting. The system is current, and the database structure can be changed depending on the object. The actually run showed that the system was running stable and normal data transfer.
