Embodiment Construction

[0054] Concrete steps of the present invention are:

[0055] 1. Design of control algorithm

[0056] (1) Control optimization problem description

[0057] The basic goal of the electronic throttle control system is that the throttle opening can quickly and accurately track the given expected target position, and at the same time, the throttle baffle is required not to collide with the limit block.

[0058] According to the control requirements of the throttle valve, the opening of the throttle valve is guaranteed y fast track on desired given value r , and in order to avoid the saturation of the actuator and ensure the smoothness of the control action, it is hoped that the rate of change of the control action It should not be too large, and at the same time, it must meet the hard constraints of the system. Therefore, the problem of electronic throttle position tracking control can be described as the following constrained optimization problem:

Abstract

The invention provides a model prediction control system for an electronic throttle valve based on FPGA, and belongs to the field of automotive electronic technology. The purpose of the invention is to provide a model prediction control system for an electronic throttle valve based on FPGA, wherein the model prediction control system can well meet control demands of a throttle valve, can be flexibly to reduce, expand and upgrade on line, and overcome shortages of an electronic control system of a present electronic throttle valve. The method of the system comprises designing a model prediction controller and implementing a control system through FPGA. The invention designs an advanced model prediction controller of a throttle valve, constraint optimization is successful, multi-target constraint control can be achieved because the throttle valve can quickly and accurately track, a good control effect is achieved. The model prediction control system for the electronic throttle valve based on the FPGA can be conveniently to upgrade, expand and maintain, the service life of a product can be prolonged, and costs of development and maintenance are reduced. Compared with a control system based on a single chip microcomputer or the like, the control system based on the FPGA is strong in anti-interference, productization is easier, and design on a special control chip can be achieved.
