摘要
The paper presents a method for logic controller synthesis based on net condition/event models of the uncontrolled plant and specifications of forbidden states. Plant models are set up in a structured and modular way. Synthesis is performed by means of a complete symbolic local backward search from the forbidden states to the control inputs. The algorithm is performed over the structure of the model; a generation of the complete state space is only required in the worst case. The result is a logic controller which can be directly implemented. Solutions for incomplete observation of states of the plant are given.
