BangBangPlant.m) and is correctly referenced in the problem formulation file with. Next is to ensure you supply a standalone dynamic file (e.g. Then run startupadigator.m in the Adigator directory and select 'adigator' for rivatives in the option file for the problem in ICLOCS2. Version 2.0: For use of Adigator with ICLOCS2 version 2, first download and install the toolbax. Despite being computationally more expensive than fintie differences, the accuracy will be exact up to machine precision. The lastest releases of SUNDIALS does not contain the MATLAB interface anymore, thus it is recommended to download version 2.6.2 from their websiteĪnd add folder sundialsTB to the MATLAB's path directory (can easily acess throuth the Set Path botton).Īdigator is a toolbox in MATLAB that uses forward mode automatic differentiation to compute the numeric derivatives of user functions. ICLOCS2 utilizes the sensitivity solver CVODES in the direct multiple shooting formulation. SUNDIALS is a SUite of Nonlinear and DIfferential/ALgebraic equation Solvers. Here are some of the additional toolboxes that may be used together with ICLOCS2 (not mandatory). Unzip the ICLOCS2 source files into the desired folder, and add the included src folder and its all subfolders to MATLAB's path directory (can easily acess throuth the Set Path botton). = optimoptions('fmincon','Display','iter','SpecifyObjectiveGradient',true,'Specif圜onstraintGradient',true,'MaxIterations',5000) To enable the use of fmincon in ICLOCS2, please adapt the following settings Therefore, we would recommend to use fmincon only for sanity checks. However this is not recommondedīecause the solution speed can be significantly slower with a higher chance of failure. ICLOCS2 also support the use the builtin fmincon function from MATLAB. Note that many (latest) versions of WORHP no longer include the MATLAB interface and is not supported. The matlab directory containing the MATLAB interface need to be added to MATLAB's path directory (can easily acess throuth the Set Path botton). This proprietary software is available from their website andĪcademic users may be able to obtain a free license. WORHP, also referred to as eNLP (European NLP solver) by ESA, is a sequential quadratic programming (SQP) based NLP solver. Licenced users are recommeded to obtain the HSL library for use of the MA57 linear solver. Windows users are recommened to install OPTI Toolbox which will have IPOPT included.Īnother option is to refer to this installation guideįrom ETH to compile the latest version of IPOPT, however note that the document may become outdated and modifications in the steps may be needed.Īlso, there are pre-compiled (despite earlier version) IPOPT mex files availble for MATLAB. Interior point based solver IPOPT is the prefered solver for ICLOCS2, and can be obtained freely from Github toghether with the MATLAB interface. Current version of ICLOCS2 supports the use of IPOPT, fmincon and WORHP for solving the NLP problems. ICLOCS2 will transcrible the optimal control problems into nonlinear programming (NLP) problems. Let us help you setup ICLOCS2 and get it working in no time.įor proper functioning of ICLOCS2, you will need to have Mathworks MATLAB version 2017a or later installed. ![]()
