Control Systems Toolbox for R Language

The Control Systems Toolbox is an R library that implements basic operations for the design and analysis of control systems.

This library started as a Google Summer of Code project (2017) and was mentored by Dr. M. Kostrun and Hans W Borchers

Installation

The package may be installed from this GitHub repository using devtools in the following manner:

install.packages("devtools") # if not already installed on your PC

devtools::install_github("benubah/control")

Features

• Model Creation: Transfer function(tf), State-space(ss) and Zero-pole-gain (zpk) models; Transfer function Expressions
• Model Conversion: tf2ss, tf2zp, ss2tf, ss2zp, zp2tf, zp2ss, tfdata, ssdata, zpkdata
• System Interconnection: append, serial, parallel, feedback, connect
• Analysis: ctrb, obsv, pole, damp, dcgain
• Design: acker, care, pid, place, lqr
• Time Response: gensig, ltitr, lsim, initial, impulse, ramp, step
• Frequency Response: ltifr, freqresp, bode and nyquist
• Plotting: lsimplot, initialplot, impulseplot, rampplot, stepplot, bodeplot, nyquistplot
• Others: c2d, ode2ss

Most fundamental features of this toolbox were developed during the Google Summer of Code 2017 and a list of functions and activities produced during this summer could be found here.

Documentation

All callable functions (including utilities) are documented and could be accessed within the R environment after installing the toolbox.
