Sistem tata udara presisi adalah sistem yang mengatur lingkungan udara yang cocok untuk peralatan ICT dalam kebinet ruang Datacenter yang khusus melayani penggunaan yang sangat penting dan kritis. Untuk mencegah kerusakan pada peralatan ICT dan pada media penyimpan akibat thermal shutdown, conductive anodic failures, hygroscopic dust failures, corrosion, dan short circuit, sistem tata udara presisi harus dapat mengendalikan temperatur dan kelembaban didalam kabinet, serta mampu beradaptasi terhadap perubahan temperatur akibat perubahan beban panas peralatan IT. ...

A multi model
predictive control and proportional-integral controller switching (MMPCPIS)
approach is proposed to control a nonlinear distillation column. The study was
implemented on a multivariable nonlinear distillation column (Column A). The
setpoint tracking and disturbance rejection performances of the proposed
MMPCPIS were evaluated and compared to a proportional-integral
(PI) controller and the hybrid controller (HC). MMPCPIS developed to overcome the
HC?s limitation when dealing with very large disturbance changes (50%). MMPCPIS provided improvements by 27% and 31%
of the ISE (integral ...

A Multiple Model Predictive Control (MMPC) approach is proposed to control a nonlinear distillation column. This control framework utilizes the best local linear models selected to construct the MMPC. The study was implemented on a multivariable nonlinear distillation column (Column A). The dynamic model of the Column A was simulated within MATLAB® programming and a SIMULINK® environment. The setpoint tracking and disturbance rejection performances of the proposed MMPC were evaluated and compared to a Proportional-Integral ...

ABSTRACT
Traditional approaches in constructing response surface models typically ignore model uncertainty. If the relationship between the input factors and output characteristics of a process is very complex, traditional model building approaches may have limited effectiveness. In this paper, we propose a multi model ensemble and then implement this ensemble model to optimize the process performance. To form a multi model ensemble, we need to determine the weights of the different models, that is, values indicating ...
