Cascade control of DC brushed motor

Master's Thesis from the year 2014 in the subject Electrotechnology, grade: Distinction, University of Newcastle upon Tyne, language: English, abstract: The aim of this project is to control speed of permanent magnet DC motor by using technique called cascade control. In this project the working of PMDC motor, H-bridge using unipolar switching scheme, PI controller in current loop and speed loop of cascade control is first studied by simulating in MATLAB software and after that practically applied cascade control on PMDC motor using flexible inverter board. In this project dsPIC30F3010 is programmed and armature current and armature voltage is controlled by inner current loop and outer speed loop of coascade control. In this project investigation of effect of anti-windup C code on drive performance is done. The flexible board has microcontroller, current sensor and H-bridge circuit on it which will be used to supply voltage to PMDC motor. As a PMDC motor, DC motor rig is used which has two identical DC motor coupled together and one motor have encoder fitted on it and other motor have tacho-generator fitted on it.
