We present a structured interior-point method for the e cient solution of the optimal control problem in model predictive control MPC . The cost of this approach is linear in the horizon length, compared with cubic growth for a naive approach. We use a discrete-time Riccati recursion to solve the linear equations e ciently at each iteration of the interior-point method, and show that this recursion is numerically stable. We demonstrate the e ectiveness of the approach b y applying it to three process control problems.

Abstract.According to the shortage of the power supply mode of equipment vehicle, a driving force generation speed control is set up to achieve vehicle self-generating when it running. System adopts the high efficiency's hydraulic volume speed-modulating circuit. A constant speed control system which composes of variable displacement pump and fixed displacement motor is researched, and the mathematical model of hydraulic system's each link is established. Using the software of Matlab/Simulink emulates the pump controlled motor system's responding situation, and results show that control system has better speed control ability. The influence of the structure parameters of speed control's performance is investigated and the research also provides the effective reference significant for the achievement of vehicle-based generator system.
