PythonLinearNonlinearControl/mpc

Model Predictive Control Tool

This program is about template, function of linear model predictive control

Documentation of this function

Linear model predicitive control should have state equation. So if you want to use this function, you should model the plant as state equation. Therefore, the parameters of this class are as following

Parameters :

• A : numpy.ndarray
  • system matrix
• B : numpy.ndarray
  • input matrix
• Q : numpy.ndarray
  • evaluation function weight
• R : numpy.ndarray
  • evaluation function weight
• pre_step : int
  • prediction step
• dt_input_upper : numpy.ndarray
  • constraints of input dt
• dt_input_lower : numpy.ndarray
  • constraints of input dt
• input_upper : numpy.ndarray
  • constraints of input
• input_lower : numpy.ndarray
  • constraints of input

We have two function, mpc_func_with_cvxopt.py and mpc_func_with_scipy.py Both function have same variable and member function. however the solver is different. Plese choose the right method for your environment

Example

Problem Formulation and Expected results

• updating soon!!

Usage

• for example

$ python main_example.py

• for comparing two methods

$ python test_compare_methods.py

Requirement
