Abstract The control of systems in the presence of constraints is an important issue in manyapplication fields because constraints always arise from physical limitations and qualityor safety reasons Moreover in practical applications disturbances are usually present andoften they are not measurable or predictable It is well known that with an unmeasuredpersistent disturbance offset free control is in general not possible In order to guaranteeoffset free control when disturbances are asymptotically constant and nonzero it isstandard practice to augment the plant model with a disturbance model and use thiscombined model to estimate the size of the disturbance However this approach is notessentially a straightforward one and on the other hand they are only able to do offset freetracking of piecewise constant reference inputs In this work a new algorithm is presented for design of Model Predictive Control Thisalgorithm enables the output to do offset free tracking of the reference input whilesatisfying system constraints in the presence of unmeasured disturbances This algorithm issplit into two parts The first part includes design of a stabilizing linear time invariantcontroller in order to initiate the offset free tracking feature due to entity of the augmenteddynamics This feature then will be completed by selecting the predictive model and designof a dynamic predictive controller Design of the model predictive controller explicitlyincludes both state and input constraints and thereby guarantees robust constraintsatisfaction In addition the algorithm to be presented is able to satisfy offset free trackingoff all reference inputs that can be presented in the form of a rational transfer functionwithout the need for estimating the disturbance
