The temperature control in chemical reactors has been shown to be of fundamental importance from product quality and process reproducibility points of view. This paper presents an experimental evaluation of multimodel approach involving a batch chemical reactor pilot. Two design features are worth to be mentioned. Firstly, an appropriate system identification approach is used to elaborate a family of control models describing the input-output behaviour of the reactor over its full operating range. Secondly, the control design is performed using a suitable fusion of robust model reference controllers. The underlying model reference control is particularly motivated by the required tracking performances.

Multimodel reference model control: an experimental validation on a chemical reactor

The mathematical modeling of continuous stirred tank reactor system is developed based on the mass and energy balances for the reactor and heating system. The system is studied by introducing step change in concentration, inlet flow, flow of heating fluid, inlet temperature and heating fluid temperature and measuring the temperature change in the reactor. In this paper, a fuzzy logic controller has been designed and evaluated. Through simulation study by using MATLAB, it has been shown that the proposed fuzzy logic controller has given an excellent tracking and regulation performance compared to that of the PID control system.

Advanced Control Using a Programmable Logical Controller

Perancangan gerakan pada robot line tracer merupakan suatu sistem yang dapat mengontrol gerakan robot sehingga robot dapat bergerak dengan baik. Untuk itu dibutuhkan kontrol PID yang dapat mengontrol robot line tracer dalam melakukan gerakan pada bidang datar berwarna putih dengan garis berwarna hitam dalam lingkungan statis, sehingga robot dapat mengikuti garis hitam tersebut dengan baik. Dari penelitian ini, diperoleh hasil pengujian dalam ruangan dengan cahaya yang redup robot dapat berjalan dengan baik pada lintasan yang lurus dan gagal pada lintasan lengkung, sedangkan pengujian dalam ruangan dengan cahaya yang terang robot dapat berjalan dengan baik pada lintasan yang lurus maupun pada lintasan lengkung.

Perancangan sistem kontrol gerakan pada robot line tracer

Batch and semi-batch chemical reactors are extensively used in polymer, fine chemical and pharmaceutical industries. The temperature control is of fundamental importance from product quality and reproductibility points of view. It is then necessary to improve the automation of these plants which are typically controlled using standard PID controllers. An autotuning PID controller is proposed and evaluated by application to a batch and semi-batch pilot plant reactor to investigate advanced control techniques. The involved control design is derived in the spirit of the partial state reference model adaptive control (PSRMAC) approach within the delta operator formulation. PSRMAC is mainly motivated by its suitable tracking capability when only a crude knowledge about the plant to be controlled is available. The delta operator formualtion is particularly motivated by the convergence of the performances to their continuous time counterpart as well as its numerical robustness when the sampling is required to be...

Adaptive linear quadratic control of batch and semi-batch cehmical reactors within the delta operator formulation

Two digital PID controllers are evaluated by application to realistic simulators involving physical models of exothermic stirred tank reactors. The first one is derived in the spirit of the partial state reference model adaptive control approach within the delta operator formulation. The second one consists in a smart PID controller which effectiveness has been already demonstrated. >
