Accordig to the trait ad performace requiremet of the CNC sero sstem, based o the traditioal PID ad kalma filter theor, a kid of special PID ler has bee desiged, usig the kalma filter to oercome the ifluece of measuremet oise ad oise i the CNC sero sstem, thus, the sstem possesses better self-adaptie abilit ad strog disturbace resistig performace. Seeral sets of experimets were carried out based o MALAB/Simulik eiromet to test the alidit of this PID ler. he damic simulatio results show that the ler achiees better performace tha the classic oe, ad it ca restrai the oise ad has better damic respose characteristics. his research gies solutio to the difficult labilit of oliear ad time-ariatio sstem, which has importat theoretical sigificace ad egieerig practical alue. 2 Published b Elseier Ltd.

Itroductio I the techolog of moder stochastic optimal ad stochastic sigal processig, sigal ad oise are ofte the multi-dimesioal o-statioar stochastic process. Because of the time-ariatio ad o-fixig power spectrum, the kalma filter theor was proposed i 96, this theor realizes the data filterig processig i computer accordig to recursie algorithm i time domai[]. Kalma filter is the best liear estimatio based o the criterio of least mea-square error, thus, it ot ol ca be applicable to the statioar sstem of scalar estimatio, but also ca be suitable for o-statioar time-ariatio sstems of the multi iput multi output. Kalma filter utilizes the state equatio ad recurrece method to estimate, ad especiall implemets easil o computer [5]. Because of the limitatios of traditioal PID ler, the parameters are difficult to adjust i the sstem that with oise iterferece, ad it is difficult to achiee ideal effect, therefore, combiig the kalma filter with the traditioal PID ler ca reduce the impact of oise o sstem, the kalma filter ca the filterig sigal to the PID ler. Cosequetl, the composite PID ler ca improe the qualit [4]. * Correspodig author. el.: address: zhpb83@63.com c 2 Published b Elseier Ltd. Ope access uder CC BY-NC-ND licese. doi:.6/j.proeg.2..73

Zhao / Procedia Egieerig 7 (2) Weibig WagPegbig Zhao/ Procedia Egieerig (2) he CNC feed sero sstem hae the strog couplig, time-ariatio ad oliear, so the strateg is er complex, desigig the better strateg ca ot ol compesate the shortcomig of hardware, but also ca improe the sstem performace[3]. he high-performace sero sstem requires the strateg hae followig characteristics, such as fast damic respose, high damic ad static precisio, ad the sstem is isesitie to chages ad disturbaces of parameters. 2. Mathematical model of CNC sero sstem 2.. Compositio of CNC sero sstem As the importat part of CNC, the mai task of feed sero sstem is to the displacemet, directio ad elocit of the moemet of executie compoet. As show i Fig., it composes of mechaical trasmissio ad electric drie sstem [3]. he former icludes worktable, tool holder, ball screw ad trasmissio gear, the latter icludes motor, drie sstem, power amplifier ad detectig elemet. So far, because of the better damic ad static performace, the high-precisio feed sero sstem usuall uses the AC sero sstem drie b PMSM. he PMSM AC sero sstem is composed of permaet maget schroous sero motor, elocit ad positio sesor, power ierter ad PWM geeratio, ad positio-elocit-curret ler. he AC motor is a strog couplig, time-ariatio ad oliear sstem, so it is difficult to.

Fig.9 PID with ad without kalma filter Aalsis from the simulatio results show that the damic respose of sstem is slow, settlig time is log, stead precisio is low, ad the mai reaso is that there is costat error ad radom error i the sigal ad the sstem model is ot er accurate. As show i Fig.9, after usig the kalma filter, the effect of sstem has bee improed distictl, because the filter process the obseratio alues b liear recurrece, it ca calculate the optimal estimates of the sstem real-timel. 5. Coclusios B itroducig the kalma filter to estimate the effectie iformatio i the alues, the accurate iformatio has bee obtaied, ad the CNC feed sero sstem has bee optimized. he simulatio results show that combiig the kalma filter ad the reasoable PID parameters, we ca obtai the stable output, shorter peak time, less oise ad fewer shocks, simultaeousl, the sstem ca reach the stable state quickl. Cosequetl, compared with the traditioal PID, the PID based o kalma filter has fast respose, better stable performace, ad high precisio, therefore, it has importat theoretical sigificace ad egieerig practical alue.
