Abstract EN
In this note, a novel multitechnique concise robust control scheme, based on the mirror mapping technique (MMT), closed-loop gain shaping algorithm (CGSA), Smith predictor (SP), and nonlinear feedback technique (NFT), is proposed for the pressure control of the liquefied natural gas (LNG) carrier insulation containment space.
Firstly, a kind of integral unstable time-delay model is obtained by linearizing the nonlinear model of the pressure maintenance system around its equilibrium.
By using the MMT and CGSA, one acquires the corresponding stable mirror mapping model of the unstable linear model and the designed controller.
And the SP is introduced to tackle the time-delay problem.
In addition, for the purpose of energy saving, the NFT is added into the control scheme.
Finally, a set of experiments has been employed to illustrate the control effects, and the results show that it can achieve satisfying performance in aspects of disturbance rejection and energy saving.
