In order to run an mpc simulation using the forces pro block, a solver first. The hybrid toolbox is a matlabsimulink toolbox for modeling, simulating, and. Generate code and deploy controller to realtime targets. In simulink requires simulink coder or simulink plc coder software. In the first control step, kwik uses a cold start, in which the initial guess is the unconstrained solution described in unconstrained. Use the builtin kwik qp solver, mpcactivesetsolver, to implement the custom mpc controller designed above.
Mpc controller solves qp problem online when applying constraints. Both solvers require the hessian to be positive definite. The software includes builtin interfaces and demos for matlabsimulink, python. If it terminates after successfully solving two qp problems, qpoases has been suc. Simulate and generate code for mpc controller with custom. Choose a web site to get translated content where available and see local events and offers.
This example shows how to simulate and generate code for a model predictive controller that uses a custom quadratic programming qp solver. Solve custom mpc quadratic programming problem and. Copy the solver template file to your working folder or anywhere on the matlab path, and rename it mpccustomsolvercodegen. Model predictive control toolbox software lets you specify a custom qp solver for your mpc controller. Although the basic version of odys qp solver software can already solve. Simulate mpc controller with a custom qp solver matlab. After designing an mpc controller in matlab, you can generate c code using matlab coder and deploy it for realtime control. Moreover, several interfaces to thirdparty software like. This example uses an online monitoring application, first solving it using the model predictive control toolbox builtin solver, then using a custom solver that uses the quadprog solver from the optimization toolbox. The odys strictlyconvex qp solver with interfaces to matlabsimulink, python, c and r. Hybrid toolbox hybrid systems, control, optimization. Based on your location, we recommend that you select.
Constrained optimization decison tree for optimization software. To generate code for mpc controllers that use a custom qp solver. Validating your simulation results or generating code with a thirdparty. Model predictive control toolbox software provides code generation functionality for controllers designed in matlab or simulink code generation in matlab. This solver is called in place of the builtin qpkwik solver at each control interval. One of the major benefits of using mpc controller is that it handles input and output constraints explicitly by solving an optimization problem at each control interval. Solving qp problems efficiently is the key enabler for deploying realtime linear and nonlinear model predictive control in industrial production although the basic version of odys qp solver software can already solve problems arising from mpc, we have developed a dedicated mpc version to further improve both the speed of execution and the memory. Solve custom mpc quadratic programming problem and generate. Odys qp solver fast and robust qp solver for embedded mpc. At the beginning of each control interval, the controller computes h, f, a, and b or, if they are constant, retrieves their precomputed values the toolbox uses the kwik algorithm to solve the qp problem, which requires the hessian to be positive definite. Qp solver simulate mpc controller with a custom qp solver simulate the closedloop response of a model predictive controller with a custom quadratic programming solver.
