Hello, I prepared my own C - function to have own simulation block. It compiles, link and load the function with no problem. But during the simulation I got (EXCEPTION_ACCESS_VIOLATION) with "scicosim" function. Attaching the function:
#include "c:\Program Files (x86)\scilab-5.4.0\modules\scicos\includes\scicos_malloc.h" #include "c:\Program Files (x86)\scilab-5.4.0\libs\MALLOC\includes\MALLOC.h" #include "scicos_block4.h" #include <math.h> #include <stdio.h> #include <stdlib.h> #define r_IN(n, i) ((GetRealInPortPtrs(blk, n+1))[(i)]) #define r_OUT(n, i) ((GetRealOutPortPtrs(blk, n+1))[(i)]) // inputs #define Ud (r_IN(0,0)) #define Uq (r_IN(1,0)) #define Tload (r_IN(2,0)) // states #define Id (GetState(blk)[0]) #define Iq (GetState(blk)[1]) #define Wm (GetState(blk)[2]) #define Theta (GetState(blk)[3]) #define dId (GetDerState(blk)[0]) #define dIq (GetDerState(blk)[1]) #define dWm (GetDerState(blk)[2]) #define dTheta (GetDerState(blk)[3]) // outputs #define Id_out (r_OUT(0, 0)) #define Iq_out (r_OUT(1, 0)) #define Te_out (r_OUT(2, 0)) //parameters #define Rs 1.01 #define Lq 0.001 #define Ld 0.001 #define ke 0.02 #define pp 2. #define Jm 0.008 #define B 0.000005 #define pi 3.14 #define sqrt3 1.732 void myPMSM_block(scicos_block *blk, int flag) { double *Te = (double *) * (blk->work); switch (flag) { case Initialization: Te = (double *) MALLOC(sizeof(double)); Te[0] = 0; break; case DerivativeState: Te[0] = 3./2.*pp/2.*(ke*Iq);// + (Ld - Lq)*Id*Iq); dId = 1./Ld*(Ud - Rs*Id + Lq*pp/2.*Iq*Wm); dIq = 1./Lq*(Uq - Rs*Iq);// - (Ld*Id + ke)*pp/2.*Wm); dWm = 1./Jm*(Te[0] - B*Wm - Tload); dTheta = Wm; break; case OutputUpdate: Id_out = Id; Iq_out = Iq; Te_out = Te[0]; break; case Ending: scicos_free(Te); break; } } After xcos block simulation I am getting within console this message: Warning !!! Scilab has found a critical error (EXCEPTION_ACCESS_VIOLATION) with "scicosim" function. Save your data and restart Scilab. Any idea how to resolve this? Thank you.
