Stabilizing gain design for PFC (Predictive Functional Control) with estimated disturbance feed-forward
نویسنده
چکیده
Abstract: PFC (Predictive Functional Control) is a simple but very effective SISO (Single-Input SingleOutput) predictive controller. A disturbance estimator is proposed based on PFC algorithm in case of nonmeasurable disturbances. The algorithm considers both external disturbance signal and internal, structural disturbances (process/model mismatch). Estimated disturbance feed-forward control can lead to instability because of the additional closed-loop of the estimator. Stabilizing technique by filtering the estimated disturbance is investigated for aperiodic processes including dead time.

In this paper CCM/CVM operation and modeling of the improved Sheppard-Taylor based power factor correction (PFC) rectifier is presented and a predictive control strategy is introduced for this rectifier. Compared with conventional boost or buck–boost PFC’s, this topology allows a better current tracking at the AC side, with a relatively reduced voltage at the DC side. Consequently, ...
متن کاملDisturbance Observer-Based Predictive Functional Critical Control of a Table Drive System
This paper addresses a control system design for a table drive system based on the disturbance observer (DOB)-based predictive functional critical control (PFCC). To empower the previously developed DOB-based PFC to handle constraints on controlled outputs, we propose to take a critical control approach. To this end, we derive the transfer function representation of the PFC controller and yield...

This article deals with the issues associated with developing a new design methodology for the nonlinear model-predictive control (MPC) of a chemical plant. A combination of multiple neural networks is selected and used to model a nonlinear multi-input multi-output (MIMO) process with time delays. An optimization procedure for a neural MPC algorithm based on this model is then developed. T...
متن کاملPredictive Functional Control with Disturbance Observer for Tendon-Driven Balloon Actuator
In recent years, Japanese society has been aging, engendering a labor shortage of young workers. Robots are therefore expected to perform tasks such as rehabilitation, nursing elderly people, and day-to-day work support for elderly people. The pneumatic balloon actuator is a rubber artificial muscle developed for use in a robot hand in such environments. This actuator has a long stroke and a hi...

Fast and accurate transient response is the main requirement in electric machine position control. Conventional cascade control structure has sluggish response due to the limitation of inner control loop bandwidth. In this paper, in order to decrease the Permanent Magnet Synchronous Motor (PMSM) transient response time it can be used reference model using feed-forward signals. In this structure...
