Project - Speed Control of a Direct Current (DC) motor

matlab coding

% this file consists of design parameters to model a dc motor

j = 0.01 ; % moment of inertia of the motor in kgm^2;

B = 0.1 ; % motor viscous friction constant in Nms;

km = 0.01; % back emf constant in v/radians/s;

Kt = 0.01; % motor torque constant in Nm/amphere;

Ra=1 ; % armature resistance in ohm;

La=0.5; % armature inductance in henry;

% nominal parameters for the spring mass constant

m = 100 ; % mass for the system ;

k = 3944.0; % stiffness constant for the system;

% Kp and Kd gains obtained from the earlier design using plave command

kp = 3.8602;
