Application of MATLAB Simulation Processes on Transfer Functions and Model Equations for Pneumatic Force-Balance Transmitter

C. P. Ukpaka, Obuah Emmanuel Chinweikpe


An investigation was conducted to examine the application of MATLAB simulation processes on transfer functions and model equations for pneumatic force-balance transmitter. A mathematical model was developed to demonstrate the relationship between time and pressure as well as displacement in proportional, derivative and integral controllers. The results obtained revealed increase in times as well as increase in displacement for proportional controller, proportional integral controller and proportional derivative controller. MATLAB 2013 software was used in monitoring, predicting and simulating the characteristics of the system. The research work demonstrates the useful of MATLAB 2013 software on evaluating the functional parameters that control transfer functions and model equations for the pneumatic force-balance transmission process.
