Hybrid Toolbox for MATLAB

The Hybrid Toolbox is a MATLAB/Simulink toolbox for modeling, simulating, and verifying hybrid dynamical systems, for designing and simulating model predictive controllers for hybrid systems subject to constraints, and for generating linear and hybrid MPC control laws in piecewise affine form that can be directly embedded as C-code in real-time applications.

The main features of the toolbox are:

Hybrid systems modelling, simulation, and analysis

Mixed logical dynamical (MLD) systems are handled as MATLAB objects, obtained from HYSDEL models.

MLD objects can be automatically converted into piecewise affine (PWA) objects.

MLD and PWA objects can be simulated in MATLAB or in Simulink.

Safety properties can be verified through reachability analysis.


Model predictive control design

Model predictive controllers based on on-line optimization (MILP / MIQP) can be designed for hybrid systems.

Quadratic and infinity norms are supported.


Explicit MPC control design

Explicit MPC controllers in piecewise affine form can be designed via offline optimization (multiparametric programming) for linear systems w/ constraints and for hybrid systems.


C-code generation

Explicit controllers can be easily exported as C-code for direct implementation and rapid prototyping, by either simply running Real-Time Workshop or by embedding the generated C code in the application.


Simulink library

Blocks are provided for: controllers based on on-line optimization, explicit piecewise linear controllers, MLD and PWA models.


Solver support

The Hybrid Toolbox supports several solvers for linear, quadratic, and mixed-integer optimization.

Note: The Model Predictive Control Toolbox for MATLAB should be installed to use the Hybrid Toolbox. For simulation of hybrid MPC controllers based on mixed-integer optimization, IBM CPLEX or GUROBI is highly recommended.
