The comparison among the simulation results, test data and early simulation results indicates the 42-component system established by this paper has made improvements against many weaknesses of the Previous simulation in an all-round way.
The model was verified by comparing simulation with test data.
The engineering team involved in a SE project is provided with various verification techniques and tools e.g. simulation, test, expertise, data analysis, traceabilty matrix, etc.
Bootstrapping is a modern, computer-intensive re-sampling approach which allows simulation of test data sets that mimic the initial original data set and the technique has been used successfully in a wide range of applications [ 23].
The results show that the multiphysics simulation model matches test data well and indicate that high fidelity models can be generated with the automatic model generation process.
Numerical simulations and test data compare well, and numerical results predict tensile forces in studs located near the steel web and in the region near stiffeners and other web restraint.
Previous robust control designs have used a single-input-single-output (SISO) architecture for position tracking, and this paper will assess the stability and performance of a multi-input-multi-output (MIMO) controller using simulations and test data from the real telescope.
A comparison of simulation results and test data demonstrated their very good agreement.
