GPOPS-II: MATLAB Optimal Control Software
GPOPS-II is the next-generation of general purpose optimal control software. GPOPS-II is a new MATLAB software intended to solve general nonlinear optimal control problems (that is, problems where it is desired to optimize systems defined by differential-algebraic equations). GPOPS-II implements the new class of variable-order Gaussian quadrature methods. Using GPOPS-II, the continuous-time optimal control problem is transcribed to a nonlinear programming problem (NLP). The NLP is then solved using either the NLP solver SNOPT or the NLP solver IPOPT. GPOPS-II represents a major advancement in the numerical solution of optimal control problems. GPOPS-II is available at NO CHARGE TO MEMBERS OF THE UNIVERSITY OF FLORIDA OR ANY STATE OF FLORIDA INSTITUTION. All others are required to pay a licensing fee for using GPOPS-II. Licenses of GPOPS-II can be purchased by clicking here.
Features of GPOPS-II
The following are some the key features of GPOPS-II:
- Allows for an extremely general formulation of the optimal control problem.
- Allows for inclusion of integral constraints and highly general boundary conditions.
- Complete first and second sparse finite-differencing of optimal control problem to compute all derivatives required by the NLP solver.
- The latest advances in mesh refinement including hp-adaptive pseudospectral methods.
- Gaussian quadrature integration methods for rapid convergence.
- Highly accurate costate estimation.
- Inclusion of the NLP solver IPOPT.
- Interface for NLP solver SNOPT included (but SNOPT itself is only provided to University of Florida or State of Florida users)
- No third-party products other than MATLAB are required.
