# PID Tuner Skill

## Purpose

The PID Tuner Skill optimizes PID controller parameters using various tuning methods to achieve desired control performance and robustness.

## Capabilities

- Process identification (step tests, relay)
- First-order plus dead-time (FOPDT) modeling
- Tuning methods (IMC, Lambda, Cohen-Coon, Ziegler-Nichols)
- Performance criteria optimization (IAE, ISE, ITAE)
- Robustness analysis
- Loop interaction assessment
- Tuning for various objectives (setpoint, disturbance)
- Bumpless transfer configuration

## Usage Guidelines

### When to Use
- Tuning new control loops
- Retuning underperforming loops
- Optimizing control performance
- Commissioning control systems

### Prerequisites
- Process in stable operation
- Loop components commissioned
- Process model or test data available
- Performance criteria defined

### Best Practices
- Start with conservative tuning
- Test in simulation first
- Validate robustness
- Document tuning rationale

## Process Integration
