How to solve an integral of a matrix?
Show older comments
Hello,
I would like to get help to solve a control system that carries an integral of the exponential matrix.
I have tried several times and have not achieved a good solution.
The final value of the variable "psi1" should be a 2x1 matrix.
Thank you for your help.
Regards

% Input variables
fsw = 1*10^6; %Frecuencia de conmutación
T = 0.5*1/fsw; %Semiperiodo
Tsamp = 1/fsw; %Periodo de muestreo, una muestra cada periodo
Po = 280; %Potencia de salida. Si la bajamos, la transición resonante es más pronunciada y el modelo menos preciso
Vg = 150; %Tensión de entrada
Vo = 12; %Tensión de salida deseada.
R = (Vo*Vo)/Po;
Nr = 1;
L = 9.5*10^-6; %Inductancia Serie
C = 1*10^-6; %Capacidad de salida.
n = 1/12; %Indice de transformación
D = (-sqrt(-(4*L*Po*Vg*Vo*T*n)+Vg^2*Vo^2*T^2)+Vg*Vo*T)/(2*Vg*Vo*T);
A1=[0 -1/(n*L); 1/(n*C) -1/(R*C)];
B1=[1/L ; 0];
t1=(1-D)*T;
syms 't'
psi1= int(expm(A1*t)*B1,t,0,t1);
