In present paper, a MIMO model of paper machine has been taken for the analysis and the different controller designing methods are applied to the model of paper machine, which is multivariable, interactive, delayed and complex process. For interaction and stability analysis, RGA and Niederlinski index is used respectively. The decoupling system is designed for MIMO model for avoiding unwanted interaction...
Several industrial chemical processes are found tobe FOPDT (first order plus dead time). The presence of deadtime makes the transfer function to be irrational and makesthe simulation and controller design very complex. In thepresent work an FOPDT model of the pH neutralizationprocess which is found in sugar mills is considered as a subjectof study and analysis. Having obtained its Padéapproximation,...
Temperature is the most critical parameter of a chemical reactor and controlling the temperature of a chemical reactor is the most challenging task. This paper presents a comparative analysis of various controllers (PID, NARMA — L2 and LQG) designed for controlling the temperature of a Continuous Stirred Tank Reactor (CSTR). The performance parameters considered for comparison are transient characteristics,...
This paper presents comparative study of VSI, CSI and ZSI-fed induction motor drive system and their control methods for dc-ac conversion. Inverters are used for dc to ac conversion for to control frequency and amplitude of output voltage at ac loads. The three topologies are connected to same specifications induction motor drive system and their performance parameters are studied. ZSI topology proves...
In this proposed study, Transformerless FPGA Controlled 2-Stage PV System is proposed for 3-phase electrical power generation. In this present scheme, to get AC power, power conditioning has been proposed in two stages; namely in first stage maximum power will be extracted and in second stage DC power will be converted into AC power. In this research paper conversion topology has been proposed for...
