IEEE Transactions on Control Systems Technology, 19(4), 772–781.

By: C. Vermillion*, J. Sun* & K. Butts

author keywords: Automotive control; decentralized control; model predictive control (MPC); powertrain control
TL;DR: This paper addresses the challenge of controlling an overactuated engine thermal management system where two actuators, with different dynamic authorities and saturation limits, are used to obtain tight temperature regulation by proposing a modular control strategy that combines model predictive control allocation (MPCA) with the use of an inner loop reference model.

Model predictive control allocation - Design and experimental results on a thermal management system

2009 American Control Conference. Presented at the 2009 American Control Conference.

By: C. Vermillion*, J. Sun* & K. Butts*

Event: 2009 American Control Conference

TL;DR: A modular control strategy that combines model predictive control allocation (MPCA) with the concepts of model reference control to design an inner loop controller that closely matches a dynamic specification for the inner loop input-output performance while addressing actuator dynamics and saturation constraints is proposed.

Modeling, Control Design, and Experimental Validation of an Overactuated Thermal Management System for Engine Dynamometer Applications

IEEE Transactions on Control Systems Technology, 17(3), 540–551.

By: C. Vermillion*, J. Sun* & K. Butts*

author keywords: Automotive control; calibration; optimal control; overactuated systems; powetrain control
TL;DR: This paper examines a particular layout for a thermal management unit and shows how the overactuation in the system may be leveraged in the presence of hard saturation constraints and different dynamic actuator authorities. (via Semantic Scholar)

2008 conference paper

Performance enhancement of modular control systems using µ synthesis

2008 47th IEEE Conference on Decision and Control. Presented at the 2008 47th IEEE Conference on Decision and Control.

By: C. Vermillion*, J. Sun* & K. Butts*

Event: 2008 47th IEEE Conference on Decision and Control

TL;DR: This paper proposes a modular control error compensator aimed at mitigating the performance degradation caused when the inner loop specifications are not achieved and shows that this compensator can be designed using μ synthesis and proposed an iterative procedure to optimize performance based on two concrete worst-case metrics.

Model predictive control allocation for overactuated systems - stability and performance

2007 46th IEEE Conference on Decision and Control. Presented at the 2007 46th IEEE Conference on Decision and Control.

By: C. Vermillion*, J. Sun* & K. Butts*

Event: 2007 46th IEEE Conference on Decision and Control

TL;DR: This paper considers the dynamic control allocation problem for overactuated systems where each actuator has different dynamic control authority and hard saturation limits and proposes a modular control design approach that derives sufficient stability conditions for the composite feedback system.
