Abstract

The objective of this work consist of combining two different control strategies. The IMC structure is used first, with SMC and then with a Linear Quadratic Regulator (LQR) to obtain two controllers. The IMC has an ideal structure to design controllers for facing processes with time delay. The combined control structures are applied over a nonlinear system having a variable delay. Finally, a feedforward controller is joined to each previous controller for improving their control performance.
