MULTIVARIABLE GENERALIED OPEN－LOOP DECOUPLING CONTROL FOR THE TEMPERATURE OF AN ELECTRIC-HEATED REACTOR

It is difficult to control the temperature of electric－heated reactor by means of single loopcontrol,because the interaction,the very large time constant and nonlinearity.Aimed at thes problem.a newcontroller,namely generalized open-loop decoupling controller is presented and successfully applied to the control of the reactor temperature.It is shown that the presented controller has not only good control perfor-mances but also strong robustness.Key words multivariable system,decoupling control,temperature control
