Abstract: 
This project researches the electromagnetic compatibility in electrical circuit by solving a problem of an all-pass filter bridge. The bridge circuit contains two resistors, two capacitors and two inductors. The output voltage is not stable because it can be influenced by a magnet movement near the inductors. In other words, the inductive voltage created by the magnet is the disturbance of the system. The final goal of the project is, when an input voltage is supplied to the bridge circuit, we have a stable output voltage with a value nearly the same as the input. By using the Root-Locus rule, a controller circuit could be designed in order to stabilize the bridge system. Because the time constant of the plant is so small, the controller has to be built by Op Amp. The project was done with the help of MATLAB Simulink and TINA program. Besides, the control theories and Op Amp properties should be studied for the purpose of designing the analog controller circuit. The thesis process is divided into 3 parts: literature reviewing, software working and hardware working.
