First of all,a first-order linear differential equation can be written as follows:y +P (x )y =Q (x )Some examples:y =ky It has P (x )=−k,Q (x )=0.(Note this one is separable).Next example is nonseparable:xy =x 2+3y Rewriting as y −3x y =x ,we can ...

For example, consider the water tank model x.=q−f(x) with interval bounds [q¯,q―] on the landmark value q and static envelopes f and f― on the unknown function f ∈ M+0. The bounding ODE system, which must have double the order of the original QDE, is x.―=q―−f―...
To illustrate how a differential equation can model a physical situation we will examine a relatively simple problem. Consider the way a hot object cools, – for example, a saucepan of milk, the water in a bath or molten iron. Each of these will cool in a different way dependent on the...

摘要: Calculation of the hydraulic coupling in the single penstock multi-machine (SPMM) is one of the main obstacles for control design of the hydro turbine governor. In order to resolve this problem, a multi-machine differential equation model suitable for co...
