Bandwidth Reduction Methods for Packetized MPC

Controller design for offloaded Model Predictive Control operating over lossy communication channels with bandwidth-efficient transmission strategies.

Overview

This methodology addresses the challenge of implementing MPC when the controller is offloaded to a remote location (edge/cloud) and communicates with the plant over a lossy network. It introduces two complementary bandwidth-reduction methods:

1. Multi-horizon MPC: Reduces optimization variables and transmitted packet size
2. Communication-rate reduction: Lowers transmission frequency while maintaining performance

Key Features

Dual Bandwidth Reduction Strategy

Method	Mechanism	Benefit
Multi-horizon MPC	Variable prediction steps	Fewer optimization variables
Rate reduction	Skip transmissions	Lower communication frequency

Theoretical Guarantees

• Recursive Feasibility: Maintained under packet loss
• Constraint Satisfaction: Guaranteed with minimal assumptions
• Reference Tracking: Performance bounds established

Methodology

Multi-Horizon MPC Formulation

Standard MPC: N uniform steps → N optimization variables
Multi-horizon MPC: Variable step sizes → fewer variables

Example:
  - Step 1-2: Fine resolution (short steps)
  - Step 3-5: Coarse resolution (longer steps)
  - Result: Same prediction horizon, fewer variables
