## Reduce steady-state parameter file (Reactor_sspar.r)
## as siso_sspar ecxept that states/states have different meaning
## Steady state for constant c_a, c_b and t=t_s and f=f_s
## Unit volume Reactor:
v_r = 1;
## The exponentials.
e_1 = exp(-q_1/t_s);
e_2 = exp(-q_2/t_s);
e_3 = exp(-q_3/t_s);
## Solve for the steady-state concentrations
## Solve for ca - a quadratic.
a = k_3*e_3; #ca^2
b = k_1*e_1 + f_s; #ca^1
c = -c_0*f_s;
c_a = (-b + sqrt(b^2 - 4*a*c))/(2*a);
## solve for c_b
c_b = c_a*k_1*e_1/(f_s+k_2*e_2);
#States (masses)
x1 = c_a*v_r;
x2 = c_b*v_r;
#Thermal state
x3 = c_p*t_s*v_r;
#Steady-state state q needed to achieve steady-state t_s
q_s = -((t_0-t_s)*c_p*f_s + e_1*h_1*k_1*x1 + e_2*h_2*k_2*x2 + e_3*h_3*k_3*x1^2);
## The two inputs at steady-state
u1 = f_s;
u2 = q_s;
## Load up the states
