Abstract

The invention discloses a parameter optimization adjusting method and system. The method comprises the steps of constructing a simulation model to be designed; obtaining an optimization parameter set according to the simulation model to be designed; calling a global optimization algorithm function, and regarding the optimization parameter set as the input to be substituted into the global optimization algorithm function so that optimization adjusting can be conducted on a parameter to be optimized and adjusted. According to the parameter optimization adjusting method and system, firstly the parameter to be optimized and adjusted is determined, the parameter to be optimized and adjusted is led out of the simulation model to be designed to be regarded as an input parameter of the simulation model to be designed, an engineering constraint request of the simulation model to be designed is converted into a constraint condition, a design index request is converted into an optimization searching index of the parameter to be optimized and adjusted, the global optimization algorithm function is scheduled to conduct automatic optimization searching, and a final adjusting result of the parameter to be optimized and adjusted is determined from automatic optimization searching process data. The parameter optimization adjusting method and system are applicable to various kinds of application occasions such as optimization of flightpath parameters and controller parameters; meanwhile, the number of the parameters to be optimized and adjusted is not limited, and parameter optimization adjusting method and system can assist a designer in improving the designing efficiency.

Description

technical field [0001] The invention relates to the technical field of algorithm design and simulation, in particular to a parameter optimization and adjustment method and system. Background technique [0002] In the process of designing and simulating the guidance and control system of an aircraft, it usually involves design issues such as flight trajectory planning, flight attitude control and flight center of mass position control. Taking flight trajectory planning and design as an example, the traditional design process is as follows: figure 1 As shown, in the traditional design process, it is necessary to judge whether the simulation results meet the design requirements. If the requirements are not met, it is necessary to return to the previous step, readjust the model parameters, and re-simulate until the simulation results meet the requirements. This traditional multi-parameter optimization adjustment needs to be adjusted manually, and the adjustment process is labor...
