CHALLENGES AND OPPORTUNITIES OF IMPLEMENTING PARALLEL COMPUTATION IN NETWORKED CONTROL SYSTEM

There is a lot of time expensive computation in advanced control, which baffles the applications of advanced control techniques. To deal with this problem, parallel computation is a promising means. By parallel computation, the execution time of advanced control application can be reduced and then its application field can be expanded. The trend of current control system is networked control system. So parallel computation can be implemented in the network of controllers. The computation fashion in the networked control system has greatly changed. In this paper, the possibility of parallel control applications based on the popular control system architecture to solve the time consuming problem related to some advanced control algorithms, is presented. And some problems of bringing parallel computation into control system also are discussed.
