a fault-tolerant control (ftc) methodology has been presented for nonlinear processes being imposed by control input constraints. the proposed methodology uses a combination of feedback linearization and model predictive control (flmpc) schemes. the resulting constraints in the transformed process will be dependent on the actual evolving states, making their incorporation in the design context ...

background: study in design to incorporate accelerated proliferation correction factors into linearquadratic and multiple-component models. materials and methods: accelerated proliferation rate correction factor has been incorporated into the linearquadratic and the multiple component models by applying accelerated exponential cell growth to explain the tumor cell kinetics and estimates proper ...

Journal: Gas Processing 2015

The present sought to draw a comparison between Model Predictive Control performance and two other controllers named Simple PI and Selective PI in controlling large-scale natural gas transport networks. A nonlinear dynamic model of representative gas pipeline was derived from pipeline governing rules and simulated in SIMULINK® environment of MATLAB®. Control schemes were designed to provide a s...

one of the main requirements for providing software security is the enforcement of access control policies, which is sometimes referred to as the heart of security. the main purpose of access control policies is to protect resources of the system against unauthorized accesses. any error in the implementation of access control policies may lead to undesirable outcomes. hence, we should ensure th...
