| Abstract: | The modeling and simulation of distributed parameter switched systems (DPSS) were discussed. By the semigroup theory, the evolution equation model of DPSS was constructed, and the system simulation method was designed. For the numerical solution of switching law related to system state which is difficult to be obtained, the general orthogonal polynomials was used to get approximate switching law and the simulation was realized. Finally, two examples are illustrated to show the feasibility and effectiveness of the proposed method. |
