PURPOSE:To fix impulse response in a short time by using M series of signals, whose autocorrelation number is close to a white noise, as an identification signal. CONSTITUTION:A signal eK obtained from a desired-value signal RK and a feedback signal YK from a process 1 is inputted to a controller 3, whose control constant is used for control arithmetic to operate the process 1 with an operation signal UK. The operation signal UK at this time contains an additional fixed signal VK composed of M series of binary signals generated by a fixed-signal generation part 4. Then, the signals eK, VK and YK are inputted to filters 6, 7 and 8. The outputs of the filters 6 and 7 are added together and inputted to an MA identification model 9, and the output of the filter 8 is inputted to an AR identification model part 10. The difference between the outputs of those model parts 9 and 10 is calculated and inputted to a control constat arithmetic part 12 via an identification arithmetic part 11 which idetifies coefficients of autoregression moving mean models successively. |
