this.s.udy examines.the track and intens.ty forecas.s.of two typical Bay of Bengal tropical cyclones.(tC) As.NI and MOCHA. the analys.s.of various.Numerical Weather Prediction (NWP) model forecas.s.[ECMWF (European Centre for Medium range Weather Forecas.), NCEP (National Centers.for Environmental Prediction), NCUM (National Centre for Medium Range Weather Forecas.-Unified Model), IMD (India Meteorological Department), HWRF (Hurricane Weather Res.arch and Forecas.ing)], MME (Multi-model Ens.mble), s.IP (s.atis.ical Cyclone Intens.ty Prediction) model, and OFCL (Official) forecas.s.s.ows.that intens.ty forecas.s.of As.NI and track forecas.s.of MOCHA were reas.nably good, but there were large errors.and wide variation in track forecas.s.of As.NI and in intens.ty forecas.s.of MOCHA. Among all model forecas.s. the track forecas. errors.of IMD model and MME were leas. in general for As.NI and MOCHA res.ectively. Als., the landfall point forecas. errors.of IMD were leas. for As.NI, and the MME and OFCL forecas. errors.were leas. for MOCHA. No model is.found to be cons.s.ently better for landfall time forecas. for As.NI, and the errors.of ECMWF, IMD and HWRF were leas. and of s.me order for MOCHA. the intens.ty forecas. errors.of OFCL and s.IP were leas. for As.NI, and the forecas. errors.of HWRF, IMD, NCEP, s.IP and OFCL were comparable and leas. for MOCHA up to 48 h forecas. and HWRF errors.were leas. thereafter in general. the ECMWF model forecas. errors.for intens.ty were found to be highes. for both the tCs. the res.lts.als. s.ow that although there is.s.gnificant improvement of track forecas.s.and limited or no improvement of intens.ty forecas. in previous.decades.but challenges.s.ill pers.s.s.in real time forecas.ing of both track and intens.ty due to wide variation and incons.s.ency of model forecas.s.for different tC cas.s.

Mathematical modelling of ball and plate s.s.em with experimental and correlation function-bas.d model validation

引用

Control theory and technology 2024年第2期22卷 326-341页

作者： t.R.Dil Kumar s.J.Mija Department of Electrical Engineering National Institute of Technology CalicutKozhikode673601KeralaIndia

the ball and plate s.s.em is.an inherently nonlinear under actuated benchmark s.s.em us.d for validating the performance of various.control s.hemes. A mathematical model depicting the dynamics.clos. to that of the s.s.em is.very much required for s.ch a tes. bed. In this.corres.ondence, the complete nonlinear model, a s.mplified nonlinear model, and a linearized model of the ball and plate s.s.em are developed. the s.s.em compris.s.a ball and plate mechanis. and a rotary s.rvo unit. the ball and plate mechanis. is.modelled us.ng the Euler–Lagrange method, whereas.the rotary s.rvo s.bs.s.em is.modelled from the firs. principles. the nonlinear model of the combined s.s.em is.developed by including the dynamics.of the s.rvo motor with gear and rolling res.s.ance between the ball and the plate. the s.mplified nonlinear model of the s.s.em is.obtained with s.itable as.umptions. the model is.linearized around the operating point us.ng the Jacobian. the validity of the developed models.is.inves.igated through correlation function analys.s. the open-loop res.ons. of the three models. viz., nonlinear, s.mplified nonlinear, and linearized models. is.analyzed in the MAtLAB/s.mulink platform. s.nce the open-loop s.s.em is.uns.able, the experimental validation of the model is.performed with a double-loop Ps. (particle s.arm optimization) PID control s.heme.
