ARCHITECTURE FOR REAL-TIME RULE-BASED CONTROL.

A method for control using rule-based search is reviewed, and a rule-based controller achieving economical real-time performance is described. Code optimization, in the form of Lisp-to-Pascal knowledge base translation, provides real-time search execution speed and a processing environment enabling highly integrated symbolic and numeric computation. With a multiprocessor software architecture specifying rule-based protocol for control task communication, and a hardware architecture providing concurrent implementation within a multimicroprocessor system, the controller realizes a set of cooperating real-time expert systems. The proposed approach appears to be applicable to a large class of complex control problems.
