# *motulator:* Motor Drive Simulator in Python

Introduction
------------
This open-source software includes simulation models for an induction motor, a synchronous reluctance motor, and a permanent-magnet synchronous motor. The motor models are simulated in the continuous-time domain while the control algorithms run in discrete time. The default solver is the explicit Runge-Kutta method of order 5(4) from scipy.integrate.solve_ivp. Simple control algorithms are provided as examples.

Installation
------------
This software can be installed using pip: 

```bash
pip install motulator
```
Alternatively, the repository can be cloned. Running `__init__.py` in the folder `motulator` allows importing the package.

Usage
-----
The following example shows how to create a continuous-time system model, a discrete-time controller, and a simulation object:
```python3
import motulator as mt

# Continuous-time model for the drive system
motor = mt.InductionMotor()     # Motor model
mech = mt.Mechanics()           # Mechanics model
conv = mt.Inverter() 	        # Converter model
mdl = mt.InductionMotorDrive(motor, mech, conv)

# Discrete-time controller 
pars = mt.InductionMotorVectorCtrlPars() 	# Dataclass of control parameters
ctrl = mt.InductionMotorVectorCtrl(pars) 	# Sensorless controller

# Create a simulation object, simulate, and plot example figures
sim = mt.Simulation(mdl, ctrl)
sim.simulate()
mt.plot(sim)
```
This example applies the default settings. However, the drive system, controller, reference sequences etc. are easy to configure, see the folder `examples` for example scripts. New system models and controllers can be developed using the existing ones as templates. More features will be added later.
