In pulsar t.ming, t.ming residuals are t.e differences bet.een t.e observed t.mes of arrival and predict.ons from t.e t.ming model. A comprehensive t.ming model will produce feat.reless resid- uals, which are presumably composed of dominat.ng noise and weak physical effect. excluded from t.e t.ming model （e.g. gravit.t.onal waves）. In order t. apply opt.mal st.t.st.cal met.ods for det.ct.ng weak gravit.t.onal wave signals, we need t. know t.e st.t.st.cal propert.es of noise component. in t.e residuals. In t.is paper we ut.lize a variet. of non-paramet.ic st.t.st.cal t.st. t. analyze t.e whit.ness and Gaussianit. of t.e Nort. American Nanohert. Observat.ry for Gravit.t.onal Waves （NANOGrav） 5- year t.ming dat., which are obt.ined from Arecibo Observat.ry and Green Bank t.lescope from 2005 t. 2010. We find t.at.most.of t.e dat. are consist.nt.wit. whit. noise; many dat. deviat. from Gaussianit. at.different.levels, nevert.eless, removing out.iers in some pulsars will mit.gat. t.e deviat.ons.

t.is paper invest.gat.s t.e design problem of a sliding mode cont.oller for linear repet.t.ve processes(LRPs) wit. a finit. pass lengt. on each pass. Under limit.d communicat.on resources, an event.riggered mechanism is implement.d from t.e sensors t. t.e cont.oller, whose t.iggered sequence is consist.nt.wit. t.e evolut.on direct.on of LRPs. t. periodically orchest.at. communicat.on bet.een t.e cont.oller and act.at.r, a round-robin scheduling mechanism is est.blished based on t.e pass lengt.. A sliding funct.on involving t.e st.t. and pass profile is const.uct.d, and t.e sliding mode cont.oller is designed using t.iggered st.t.s and pass profile signals. Feasible cont.oller gains are at.ained t. ensure t.e st.bilit. of t.e result.nt.closed-loop syst.m. Finally, t.e proposed st.at.gy is implement.d for a mult.-roll met.l rolling process.
