Hello friends, good day. I'm doing an algorithm but it's not working well. Annex my code. I am evaluating two functions (V1, V2), each time they go through zero a pulse is activated, when both pulses coincide (either 0 or 1) a third pulse is activated which determines the state of a variable (Cvar). That variable (Cvar) must modify the function V1. The problem is that my code is not running.
Can you help me please? Could you tell me where my mistake is? Thank you. Have a nice day.
model practica
Real V1;
Real V2;
Real u;
Real u1;
Real Cvar;
Real y;
Real y1;
Real y2;
Real y3;
Boolean cross1;
Boolean cross2;
parameter Real Cp = 2;
parameter Real Cs = -2;
equation
V1 = 5 * sin(60 * time)* Cvar;
V2 = 5 * sin(100 * time);
cross1 = V1 < 0.0;
cross2 = V2 < 0.0;
u = if cross1 == true then 1 else 0;
u1 = if cross2 == true then 1 else 0;
y = (-1 * u) + (-1 * u1) + 1;
y1 = u * (-u1) * (u1 * (-u)) + 1;
y2 = y + y1;
y3 = y2 + y1 - 2.5;
if y3>0 then
Cvar = Cp;
else
Cvar = Cs;
end if;
end practica;
