A second-order cone programming problem has the form. subject to the constraints. f, x, b, beq, lb, and ub are vectors, and A and Aeq are matrices. For each i, the matrix Asc ( i ), the vectors bsc ( i) and dsc ( i ), and the scalar γ ( i) are in a second-order cone constraint that you create using secondordercone.
Quadratic Programming and Cone Programming. Solve problems with quadratic objectives and linear constraints or with conic constraints. Before you begin to solve an optimization problem, you must choose the appropriate approach: problem-based or solver-based. For details, see First Choose Problem-Based or Solver-Based Approach.
2017-8-23 · for the cone crusher and for prototyping, parameters of a PID controller were determined in the Simulink/MATLAB® environment. The simulation involved the optimisation of the control model as a function of the cavity level of and the power drawn by the cone crusher. A self-tuning control algorithm at PLC and SCADA level of control was then tested.
