The calculated operating point is C_A = and T_K = 373 K. Notice that the
steady-state coolant temperature is also given as 299 K, which is the nominal value of
the manipulated variable of the MPC controller.
To specify:
• Values of known inputs, use the Input.Known and Input.u fields of opspec
• Initial guesses for state values, use the State.x field of opspec
