Abstract :
An algorithm is proposed to solve the linear-quadratic control problem with linear inequality constraints. This algorithm provides an alternative to the use of quadratic programming for predictive control; it is computationally efficient and computes a feedback control when the optimal control does not lie on a constraint. The performance of the algorithm for an evaporator model is presented along with comparisons to model algorithmic control.
