Abstract: We examined a design approach for a PID controller for a nonlinear ball and beam system. Main objective of our research was to establish a nonmodel-based control system, which would also not be dependent on a specific ball and beam hardware setup. The proposed PID controller setup is based on a cascaded configuration of an inner PID ball velocity control loop and an outer proportional ball position control loop. The effectiveness of the proposed controller setup was first presented in simulation environment in comparison to a hardware dependent PD cascaded controller, along with a more comprehensive study on possible design approach for optimal PID controller parameters in relation to main functionality of the controller setup. Experimental real-time control results were then obtained on a laboratory setup of the ball and beam system on which PD cascaded controller could not be applied without parallel system model processing.Keywords: position control, nonlinear system, position errorPublished in DKUM: 15.06.2017; Views: 1171; Downloads: 441 Full text (3,23 MB)This document has many files!

Abstract: V diplomskem delu je predstavljena zasnova algoritma mehkih regulatorjev v programskem jeziku C in izvedba povezave zasnovanega algoritma z vizualnim vmesnikom za snovanje mehkih regulatorjev v programskem orodju MATLAB. Kot ciljni sistem aplikacije zasnovanega algoritma je predstavljen sistem regulacije ravnovesja valjčka na letvi, v okviru katerega je prikazan postopek oblikovanja ciljnega mehkega regulatorja in njegov prenos na druge računalniške platforme. Izvedena je bila verifikacija zasnovanega algoritma na dveh računalniških platformah in regulacija ravnovesja položaja valjčka na letvi z zasnovanim algoritmom mehkega vodenja.Keywords: snovanje mehkih sistemov vodenja, algoritem mehkega vodenja, vizualni vmesnik, regulacija ravnovesjaPublished in DKUM: 06.01.2011; Views: 2107; Downloads: 202 Full text (1,73 MB)
