The Mathematic Simulation Of Twin Engine System And Research On Intelligent Control Process

Along with the development of ship and submarine, the power plant of some special ships and submarines with one kind of power can not do well in their work field, especially in some martial ships and submarines, which brought on the naissance of combined power plant. Under the development of combined power plant since 1960s, CODAD(combined diesel and diesel), CODAG(combined diesel and gas turbine) and CODOE(combined diesel or electromotor) had got a wide application.Twin engine incorporation is the key point of combined power plant, how to make the twin engine works, how to make the switching between single engine work state and twin engine work state, how to make the work state switching between the two engines by using the twin engine system and how to get a good power distribution when the system in any work states are the problems should be solved in the research of twin engine system.In this thesis, firstly, I founded a model of twin engine incorporation system based on different diesel engines, and got the simulation result of two work states in the twin engine system, single diesel engine work state and switching work state between single diesel engine and twin engine, then got a credible model of twin engine system by a lot of analyzing and simulation experiment; secondly, I mainly analyzed the control strategy of twin engine experiment system, proposed some kinds of control strategy based on speed control device, got the simulation result by the simulation of every control strategy; besides these, I had done some research of CODAE which was widely used in normal power submarine by the practical work state of normal power submarine. And then I made the model of electromotor used in submarine and CODOE system, in order to get the simulation result of smooth switching between the work state of single electromotor and the work state of single diesel. At last I got a credible model of CODOE by analyzed the simulation result.The model I got can commendably show the work states of twin engine system. We can optimize the design of twin-engine system by doing some experiment on the twin engine system model, analyzing the simulation results of the experiments when the system in different work states.
