### **Slide 1: Robust Control Foundations**
|
||||||
|
|
||||||
|
**Assertion:** Robust control ensures stability despite system discrepancies.
|
||||||
|
**Evidence:**
|
||||||
|
|
||||||
|
- Controllers are based on physical models that differ from real systems.
|
||||||
|
- Robust control analyzes resilience to system perturbations.
|
||||||
|
- Evolved from single-input single-output to multi-input multi-output systems.

### **Slide 2: Structured vs. Unstructured Perturbations**
|
||||||
|
|
||||||
|
**Assertion:** Robust control addresses structured and unstructured perturbations differently.
|
||||||
|
**Evidence:**
|
||||||
|
|
||||||
|
- **Structured:** Based on physical tolerances (e.g., spring rates).
|
||||||
|
- **Unstructured:** Accounts for unmodeled dynamics and broader uncertainties.

### **Slide 3: Disk-Based Unstructured Uncertainty**
|
||||||
|
|
||||||
|
**Assertion:** Disk-based perturbation quantifies unstructured uncertainties.
|
||||||
|
**Evidence:**
|
||||||
|
|
||||||
|
- Key equation: $\tilde{P} = (1 + \Delta W_2) P$
|
||||||
|
- $P$: Nominal plant.
|
||||||
|
- $\Delta$: Perturbation transfer function.
|
||||||
|
- $W_2$: Uncertainty envelope.
|
||||||
|
- Conditions for $W_2$ and $\Delta$:
|
||||||
|
- $\left| \frac{\tilde{P}(j\omega)}{P(j\omega)} - 1 \right| \leq \beta |W_2(j\omega)|$
|
||||||
|
- $||\Delta||_\infty \leq \beta$.
|
||||||
|
|
||||||
|

### **Slide 4: Current Limitations in Robust Control**
|
||||||
|
|
||||||
|
**Assertion:** Current methods lack discrete examples of unstructured perturbations.
|
||||||
|
**Evidence:**
|
||||||
|
|
||||||
|
- $\Delta$ is undefined for experimental robustness verification.
|
||||||
|
- Structured uncertainties are used experimentally but neglect unmodeled dynamics.

### **Slide 5: Diffusion Models as a Solution**
|
||||||
|
|
||||||
|
**Assertion:** Diffusion models can generate unstructured perturbations.
|
||||||
|
**Evidence:**
|
||||||
|
|
||||||
|
- Forward process transforms data to Gaussian distribution.
|
||||||
|
- Reverse process generates approximations of target data.
|
||||||
|
- Applications in protein folding, training data generation.

### **Slide 6: Parallels Between Diffusion Models and This Project**
|
||||||
|
|
||||||
|
**Assertion:** Diffusion models address sparse perturbation generation in engineering.
|
||||||
|
**Evidence:**
|
||||||
|
|
||||||
|
- Diffusion models create diverse training data from sparse sets.
|
||||||
|
- Proposed approach: Generate unstructured perturbations from structured sets.
