FOR MIMO SYSTEMS SELECT THE: SYSTEM TO SIMULATE CONTROLLER TO BE USED PARAMETERS OF MPC SET: DURATION REFERENCE TO REACH CONSTRAINTS NOISE DISTURBANCES RESULT: OUTPUTS , U , DU

The interface is divided in three different parts: SYSTEM: This part loads the system file to be simulated, changes its properties (matrices) and saves a system created by the user in a file. CONTROLLER: It sets the kind of MPC controller to be used, and allows changing the specific tuning parameters, such as horizons or weighting matrices. EXPERIMENT: It establishes the main features of the simulation: time, reference parameters, constraints, noises, disturbances and graphics to be showed

The following forms of modelling a system are accepted by IMPACT. 1. Carima Model. A and B model the system, and the delay factor (z-d) have been integrated in B. 2. Step Response Model (DMC) The variable gninputs contains the inputs of the system 3. Space State Model the variables Mm, Nm and Qm. (PFC and SSMPC) Error Modelling: Ap, Bp for the CARIMA--- gp for the Step response--- Mp, Np and Qp for State Space sinfo: General information about the system in a cell array 2 variables for reference: Constant: vrefc Variable: vrefv
