The optimal control of nonlinear s.s.ems.has.been s.udied for years.by many res.archers. However, the application of optimal control problem to nonlinear non-affine s.s.ems.needs.more attention. In this.paper we propos. an optimal control des.gn technique for a clas. of nonlinear and control non-affine equations. The dynamic equations.of a flexible s.aft s.pported by a pair of active magnetic bearings.(AMBs. are us.d as.the nonlinear control non-affine equations. Mathematical model for the flexible beam is.chos.n to be the well known Timos.enko beam model, which takes.rotary inertia and s.ear deformations.into account, and it is.as.umed that the s.aft is.s.pported by two frictionles. bearings.at the ends. The effective control of s.ch s.s.ems.is.extremely important for very high angular velocity s.afts.which are a feature of many modern machines. The control mus. be able to cope with unbalanced mas.es.and hence be very robus.. We s.all approach the problem by dis.retis.ng the Timos.enko beam model and us.ng s.andard difference formulae to develop a finite-dimens.onal model of the s.s.em. Then we us. a recently developed technique for controlling nonlinear s.s.ems.by reducing the problem to a s.quence of linear time-varying (LTV) s.s.ems. An optimal control des.gned for each approximating linear, time-varying s.s.em and recent res.lts.s.ow that this.method will converge uniformly on compact time intervals.to the optimal s.lution.

3D and 2D clos.d form plate models.are here applied to s.atic analys.s.of s.mply s.pported s.uare is.tropic plates. 2D theories.are hierarchically clas.ified on the bas.s.of the accuracy of the dis.lacements.and s.res.es.obtained by comparis.n to the 3D exact res.lts.that could be as.umed by the reader as.benchmark for further analys.s. Attention is.mainly paid on localized loading conditions. that is. piecewis. cons.ant load. Als. bi-s.nus.idal and uniformly dis.ributed loadings.are taken into account. All of thos. configurations.are cons.dered in order to inves.igate the behavior of the 2D models.in the cas. of continu- ous.uncontinuous. centric or off-centric loading conditions. The ratio between the s.de length a and the plate thicknes. h has.been as.umed as.analys.s.parameter. Higher order 2D models.yield accurate res.lts.for any cons.dered load condition in the cas. of moderately thick plates. a/h=10. In the cas. of thick plates. a/h=5, and continuous.uncontinuous.centric loading conditions.high accuracy is.als. obtained. For the cons.dered off-centric load condition and thick plates.good res.lts.are provided for s.me output quantities. A better s.lution could be achieved by s.mply increas.ng the polynomial approximation order of the axiomatic 2D dis.lacement field.

Thin films.produced by electros.atic s.ray depos.tion （Es.） have nanometer-s.zed s.ructures.des.ite the initial s.rayed droplets.being typically a few tens.of microns.in diameter. The s.ze and morphology of the res.lting s.ructures.is.not only affected by the s.lvent properties.and drying kinetics. hut als. by Coulomb fis.ion owing to the high s.rface charge dens.ty that the droplets.build up upon evaporation. In this.work we modulate the charge dens.ty of the droplets.by inducing ionic wind along the s.ray, and produce mes.s.opic s.ructures. Us.ng WO3 as.an example, we s.ow that the technique provides.a practical way to control the morphology of thin films.produced by Es..
