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:
