• Key Capabilities

Wolfram technologies include thousands of built-in functions that let you:

• Compute the state-space model of a system described by difference or differential equations and any algebraic constraints
• Analyze the stability of a system using built-in frequency-response tools, computing the poles or solving a Lyapunov equation
• Simplify models of systems with interconnected components using block-diagram reduction
• Manipulate linear models as transfer-function or state-space data objects
• Interactively analyze the system behavior as parameters are varied
• Employ classical techniques such as Bode, Nyquist, Nichols and root locus plots to analyze and design control systems
• Evaluate the controllability and observability properties of a system
• Compute state-space transformations to obtain decompositions that are controllable, observable, minimal or balanced
• Obtain continuous-time equivalents of discrete-time systems for analysis and design
• Develop feedback laws to enhance the performance of dynamic systems
• Design and analyze systems with time delays and algebraic equations
• Automatically compute design quantities including closed-loop transfer functions, PID parametrizations and more
• Estimate unmeasured states or noisy measurements
• Directly obtain models of controllers and estimators that can be easily assembled to form a closed-loop system for further simulations
• Discretize continuous-time feedback algorithms for real-time implementation

Does your current tool set have these advantages?

• Directly input both transfer-function and state-space models in natural form
  Matlab allows you to specify transfer-function models only as a matrix of row vectors
• Analyze symbolic and numeric systems
  Matlab handles numeric systems only
• Fully automated precision control and arbitrary precision arithmetic to ensure accurate results
  Matlab and other systems relying on machine arithmetic can show critical errors due to numerical accuracy failure
• Instant interface construction to test a control system interactively for different scenarios
  Unique to Wolfram technologies
• Free-form linguistic input produces immediate results without the need for syntax
  Unique to Wolfram technologies
• Automated algorithm selection to get accurate results quickly—sometimes switching mid-calculation for further optimization
  Other computation systems like Matlab make you analyze your equations manually to determine which function to apply
• Control systems functionality is well integrated with the core Wolfram Language and more than 20 built-in application areas, such as signal processing, time series, image processing, wavelets, linear algebra and more
