[00408] Reducing Complexity of a Population Balance Model for Synthesis of Composite Polymer Particles

- Abstract : An accurate prediction of the formation of polymer particles is vital for synthesis of high quality materials, but still not feasible due to its complexity. We present a Population Balance Equations model as a tool targeting the task. Aimed to enhance model performance, we derive a quantitative criterion for locating regions of “slow” aggregation among particles. Within such a regime, the aggregation terms can be neglected and computational efficiency improves by several orders of magnitude.

[01651] Coagulation equations for non-spherical clusters
- Session Time & Room : 1D (Aug.21, 15:30-17:10) @F311
- Type : Contributed Talk
- Abstract : We study the long-time asymptotics of a coagulation model describing the evolution of a system of particles characterized by volume and surface area. The aggregation mechanism takes place in two stages: collision and fusion of particles. A particularity of the system is that, for some fusion mechanisms, the particle distribution describes a system of ramified-like particles. Moreover, we prove that we are able to recover the standard coagulation equation in the case of fast fusion.

[01564] Extended Observer-based Control for Interval-type-2 Fuzzy Systems Under Event-Triggered Scheme

- Abstract : The problems of disturbance rejection and fault tolerant control for interval-type-2-fuzzy systems are investigated by utilization of a generalized extended state observer. To be specific, the system states along with disturbances and actuator faults are simultaneously reconstructed by the implemented observer. Besides, an observer-based event-triggered scheme is implemented to mitigate the communication burden. Furthermore, the asymptotic stability criteria for the constructed system are formulated. Consequently, the theoretical declarations are authenticated by prevailing numerical simulation results.

[01550] Stabilization and State Estimation of Semi-Markovian Cyber-Physical Systems via Time-Triggered Control
- Session Time & Room : 1D (Aug.21, 15:30-17:10) @F311
- Type : Contributed Talk
- Abstract : The issues of input-output finite-time stabilization and state estimation for a class of semi-Markovian switching cyber-physical systems with cyber-attacks are investigated. Primarily, immeasurable states are estimated by designing a mode-dependent observer. Further, based on the observer information, mode-dependent time-triggered controller is developed to ensure that the resultant system is input-output finite-time stable. Finally, the efficacy of proposed result is demonstrated through a numerical example.
