【Abstract】 Different loop configuration methods of DCS are introduced,including the POL programming for digital controllers,fill-in-the-form for DCS systems,and graphics linking for FCS.And their internal mechanisms are also revealed.Implementation technologies of input/output compensation,adaptive control functions,and other important & advanced control strategies adopted in these three different control systems are compared and studied.Finally,it is pointed out that the future development of the DCS control systems will depend more upon the new control concepts and strategies.更多还原
