Offset-free Nmpc with Robust Constraint Satisfaction Using Model-error Modeling

Robustness and offset-free tracking remains a challenge in the field of nonlinear model predictive control (NMPC) in the presence of plant-model mismatch. This paper focuses on offset-free tracking with robust constraint satisfaction using NMPC. In the proposed approach, the discrepancy between the plant and a fundamental model is captured using a model-error model. The fundamental model is aug...

طراحی کنترل کننده پیش بین سیستم بویلر- توربین

A nonlinear model predictive control (NMPC) algorithm based on neural network is designed for boiler- turbine system. The boiler–turbine system presents a challenging control problem owing to its severe nonlinearity over a wide operation range, tight operating constraints on control move and strong coupling among variables. The nonlinear system is identified by MLP neural network and neur...

Offset-free Nonlinear Model Predictive Control Based on Moving Horizon Estimation for an Air Separation Unit

Air separation units (ASU) pose a classic problem for nonlinear system control. This paper proposes a framework that integrates nonlinear model predictive control (NMPC) and moving horizon estimation (MHE). We prove that the proposed method achieves offset free regulatory behavior, even in the presence of plant-model mismatches. If the plant uncertainty structure is known, the proposed framewor...

Offset-Free Model Predictive Control for Output Voltage Regulation of Three-Phase Inverter for Uninterruptible Power Supply Applications

This paper proposes an offset-free model predictive control (MPC) method for output voltage regulation of the three phase inverter for an uninterruptible power supply (UPS) application. A use of a disturbance observer (DOB) is made to estimate the unknown disturbance caused by the load current and a plant-model mismatch. The proposed MPC optimizes the one step ahead cost function. The online co...

Incremental and Positional Generalized Predictive Controller for Offset Free Reference Tracking

The traditional design of the Generalized Predictive Control (GPC), to deal with setpoint changes and tracking reference (denoting offset free), is to use an integral control weighted or an incremental plant model. The purpose of this paper is to derive an alternative way of GPC synthesis, from a positional plant model to cover zero steady-state offset, involving the selection of an integral po...
