Abstract:
A method for simulation modeling where the simulation model includes individual blocks in a block diagram structure wherein each of the individual blocks include equation sets of a physical model, comprising:configuring said blocks in a block diagram structure; utilizing commercial simulation software to solve said equation sets of said blocks; ordering said blocks in said block diagram structure to allow for waveform relaxation of sets of variables of said blocks, including mixing a reference input signal and an error signal to generate non-relaxed variables; converting the non-relaxed variables into input relaxation variables through waveform relaxation; processing the input relaxation variables with a high fidelity plant model, generating non-relaxed output variables with the high fidelity plant model, converting the non-relaxed output variables into output relaxation variables through waveform relaxation, and providing the output relaxation variables to a low order controller that generates the error signal; and designing the low order controller with said blocks to minimize the error signal, wherein the low order controller controls a system for manufacturing.
