I am trying to add a reset input to a custom integrator block using simscape. If the reset input is 1, the integrator will function normally and if the reset input is 0 it will reset to the initial condition. To achieve this I was attempting to set variable x to the initial condition (x0) when "reset == 0" but do not know how to populate the else condition to keep x the same if "reset == 1" ("if" must be accompanied by "else" in simscape language according to documentation). I tried setting x == x but this did not work. The code I have is written below. Any help would be greatly appreciated.
inputs
I = { 0, '1' };
r = { 0, '1' };
end
outputs
O = { 0, '1' };
end
parameters
x0 = { 0, '1' };
end
variables(Access = public)
x = { 0, '1' };
end
function setup
x = x0;
end
equations
if r <= 0
x == x0;
else
end
x.der == I * { 1, '1/s' };
O == x;
end
