Implementation of Linear Model Predictive Control Using a Field Programmable Gate Array

Free registration required

Executive Summary

The paper investigates the design of a field programmable gate array based custom computer architecture solution for implementing model predictive control. The solution employs a primal logarithmic-barrier interior-point algorithm in order to handle actuator constraints. The solution also incorporates practical aspects of a control algorithm including state observation and data sampling. The resulting circuit is profiled by application to a disturbance rejection control problem of a 14'th order lightly damped flexible beam structure with actuator constraints. This is achieved at 2 kHz sampling frequency and with 16-sample prediction horizon.
