This paper presents the development of a novel control law with parameter updating for trajectory tracking in a boiler-turbine system, which is a MIMO system where all state variables are strongly coupled. The proposed controller is simple and based on comprehensible concepts. Its design consists in representing the mathematical model using numerical methods, and then the control actions are computed through a linear algebra technique to accomplish the target of trajectory tracking control, by last, the parameter updating is based in the Lyapunov theory. The advantages of this method are the condition for the tracking error tends to zero, and the calculation of control actions, are obtained simply by solving a system of linear equations. Besides, the control technique has the ability to follow trajectories for two outputs simultaneously.
