| Abstract: | The problem of realtime online continuous solving numerical method of an nonlinear equation F(x(t),V(t),t)=0 with the V(t) is continuously varying is discussed, which is used to build a soft instrument in the chemical process. A limited search genetic algorithm and its improving algorithm are put forward according to the characteristic of online continuous solving of nonlinear equation. A selfadapting factor is introduced to solve the initial value problem. Simulation results of an industrial model show that the derived algorithm is correct. |
