Optimal Experiment Design for Identification
Research Guide
What is Optimal Experiment Design for Identification?
Optimal Experiment Design for Identification designs input signals to maximize parameter estimation precision in system identification under constraints and model uncertainty.
This subtopic develops D-optimal, Bayesian, and sequential designs for adaptive experimentation in control systems. Key methods minimize experimental costs while enhancing data informativeness (Bombois et al., 2006; 229 citations). Over 10 seminal papers span kernel methods and Gaussian processes (Pillonetto et al., 2014; 720 citations).
Why It Matters
Optimal designs reduce identification experiments in control engineering, minimizing costs for accurate models in robotics and process control (Deisenroth et al., 2013; 640 citations). Bombois et al. (2006) show least costly experiments improve controller performance by optimizing input signals under noise constraints. Applications include adaptive systems where sequential designs update based on prior data (Pillonetto et al., 2010; 223 citations), enabling efficient modeling in uncertain environments.
Key Research Challenges
Model Uncertainty Handling
Designs must account for unknown model structures during input selection. Bayesian approaches integrate prior uncertainty but increase computational load (Pillonetto et al., 2014). Sequential methods adapt but require real-time optimization (Bombois et al., 2006).
Constraint Incorporation
Practical limits on inputs, actuators, and noise complicate D-optimal criteria. Bombois et al. (2006) address least costly designs under control-oriented constraints. Balancing identification and control performance remains unresolved (Schoukens and Pintelon, 1991).
Computational Scalability
High-dimensional systems demand efficient optimization for experiment design. Kernel methods scale poorly with data size (Pillonetto et al., 2010). Gaussian processes offer data efficiency but struggle with real-time adaptation (Deisenroth et al., 2013).
