## Description

This MCP server provides specialized engineering tools for designing industrial process control loops. It allows AI agents to analyze process dynamics and determine critical hardware and control parameters. Use `calculate_controller_tuning` to find optimal PID gains, `size_control_valve` to determine required valve capacity, `select_sensor_hardware` to match sensors to process environments, and `analyze_loop_stability` to assess oscillation risks based on dead time and process lag.

## Tools

### analyze_loop_stability
Evaluates if a designed loop will be stable given the process lag and dead time

### calculate_controller_tuning
Determines the optimal PID parameters for a given process model

### select_sensor_hardware
Recommends a sensor type based on the process requirements and environment

### size_control_valve
Determines the required valve capacity to meet process flow demands

## Prompt Examples

**Prompt:** 
```
Calculate the PID tuning for a process with a gain of 1.5, time constant of 10, and dead time of 2 using Ziegler-Nichols.
```

**Response:** 
```
The calculated proportional gain is 6.0, integral gain is 1.2, and derivative gain is 0.75, with a stability margin of 0.85.
```

**Prompt:** 
```
What valve size do I need for a flow rate of 50 units, a pressure drop of 15, and fluid density of 1.0?
```

**Response:** 
```
The required Cv is 25.4, and the recommended valve size is a 2-inch globe valve with an operating range of 40-80%.
```

**Prompt:** 
```
Is a loop with a proportional gain of 4.0, time constant of 5, and dead time of 1 stable?
```

**Response:** 
```
The loop is stable with a stability ratio of 0.8 and a low oscillation risk.
```

## Frequently Asked Questions

**How do I calculate PID parameters?**
You can use the `calculate_controller_tuning` tool. Provide the process gain, time constant, dead time, and your preferred tuning method like Ziegler-Nichols.

**Can I check if my control loop is stable?**
Yes, use `analyze_loop_stability` by providing the proportional gain, time constant, and dead time to evaluate oscillation risk.

**How do I select the right sensor for my process?**
Use the `select_sensor_hardware` tool. It recommends hardware based on the measured variable, required accuracy, and environmental severity.
