In this paper, the two-input fuzzy logic controller (FLC) and proportional -integral-derivative (PID) controller for boost converter output-voltage regulation are proposed by using Siemens Programmable Logic Controller (PLC). Here the output voltage has been used as a closed loop feedback to determine the output voltage error (e) and the change in error (∆e) as two inputs to the controller. The elements of the boost converter as inductance and capacitor have been selected to insure continues operating mode (CCM) and low output voltage ripple. The proposal is implemented by using Programmable Logic Controller (PLC) on 150 watts prototype and compare (FLC) with (PID) results. The experimental results show that the FLC has a good output voltage response compare with PID controller response.

In this paper, we present a new programmable chaotic circuit based on the dynamical chaotic system introduced by E. Lorenz. The design and realization of the model are accomplished by using a programmable logic controller (PLC). The system can be modeled and realized with a structured texted. The nonlinear differential equations of Lorenz model are solved numerically. The generated chaotic signal by using PLC is applied to a single phase induction motor via a variable frequency drive to create a chaotic perturbation in the experiments of liquid mixing. Colorization liquid experiments shows that the generated chaotic motion effectively makes an enhancement of the mixing process in the stirred-tank mixer model in our laboratory.
