The past decades saw a remarkable development in control systems used in industry. Those excellent control systems include PLC system, DCS system and FCS system. They are widely used in industry and bring great benefits to our society. However, those control systems are too expensive in investment, and their architectures can't satisfy today's requirement. This dissertation is based on the author's research in "R&D on PC based control software system". It discusses the development of control systems, the supporting environments and architecture of PC based control system, schematic design of PC based control system and detailed design and realization of PC based control system. The dissertation is divided into five chapters, which includes: 1, the development of control systems and the strongpoint and shortcoming of different control systems; 2, introduction of the supporting environment and architecture of PC based control system; 3, introduction of the schematic design of PC based control system; 4, the detailed design and implementation of PC based control system; 5, At last, the summary of the dissertation is given, and besides, some ideas and advice for the next aim of current system are listed. The main contribution includes: 1, Do in-depth investigation of existing related software products and do research in related national standards and international standards; 2, According to the requirements of control systems used in medium and small plants, put forward the requirement of PC based control software system; 3, Give a whole solution to PC based control software system independently; 4, Implement a prototype of PC based control software system and do significant attempts in the scheduling of control system.
