pysimlink 1.2.0.dev4

Compile, run, and interact with Simulink models natively in Python!

PySimlink is a python package that automatically compiles Simulink codegen files into a simple interface that you can interact with in Python!

With this package, you can:

• Interact with the internals of your Simulink model
• Run the model in "accelerator mode"
• Send and receive data in the form of numpy arrays
• Run multiple instances of the same model

All without requiring a MATLAB runtime on the target machine! No C/C++ programming required!

To get started, you either need a copy of the generated model you want to simulate or, to generate the code yourself, you need the Simulink Coder. There are some limitations, namely that your model must use a fixed step solver (a requirement of the grt target).

Demo

Read Signal Values

from pysimlink import Model

model = Model("my_awesome_model", "model.zip")
model.reset()

for i in range(len(model)):
    model.step()
    signal_val = model.get_signal(block_path="Constant1", sig_name="Signal1")
    print(signal_val)

Change Block Parameters

from pysimlink import Model
import numpy as np

model = Model("my_awesome_model", "model.zip")
model.reset()

new_param = np.eye(3)
model.set_block_param(block="Constant1", param="Value", value=new_param)

Change a Model's Final Time Step

from pysimlink import Model

model = Model("my_awesome_model", "model.zip")
model.reset()
model.set_tFinal(500)

print(model.tFinal)
