摘要： A closed-loop actuator control system includes a single PI controller for controlling one or more actuators to minimize an error between an engine operating parameter value and a reference parameter value. In multiple actuator systems, the control system of the present invention is operable to drive one actuator to its upper limit before transferring control to the next actuator. The proportional gain block of the PI controller preferably includes a bumpless gain feature operable to limit the rate of change of the proportional gain to thereby provide smooth gain scheduling. A feedforward block may optionally be included that preferably includes the bumpless gain feature. The actuator control system further includes anti-windup logic operable to disable the PI integrator if the actuator drive signal is upper or lower limit bounded and the error signal is greater or less than zero respectively, thereby creating dynamic saturation of the PI integrator.

摘要： The present invention relates to a system and method for managing the operation of a turbocharger and is responsible for controlling the turbocharger to cause a desired air mass flow to be provided to the engine and for protecting the turbocharger from excessive shaft speed and excessive turbine inlet temperature. The protection modes have higher priority than the performance control. First, turbocharger shaft speed is checked against a programmable limit, and the turbocharger is adjusted to bring the speed under control if its speed exceeds this limit. If the speed is not above the limit, the turbine inlet temperature is checked against a second programmable limit. If the turbocharger inlet temperature is above the predetermined limit, the turbocharger is adjusted to bring the inlet temperature under control. If, after either of these adjustments are made, the predetermined limits are still exceeded by the turbocharger, then the system invokes a derating of the fueling to the engine in order to protect the turbocharger. If none of the limits have been exceeded, then the system operates the turbocharger to provide the desired air mass flow to the engine in order to maximize engine performance.
摘要翻译：本发明涉及一种用于管理涡轮增压器的操作的系统和方法，并且负责控制涡轮增压器以使发动机提供所需的空气质量流量并保护涡轮增压器免受过大的轴速度和过大的涡轮机入口温度。保护模式的优先级高于性能控制。首先，根据可编程限制检查涡轮增压器轴速度，并且如果涡轮增压器的速度超过该限制，则调节涡轮增压器以使速度得到控制。如果速度不超过极限，则涡轮机入口温度将针对第二可编程限制进行检查。如果涡轮增压器入口温度高于预定极限，则调节涡轮增压器以使入口温度得到控制。如果在进行这些调整之一之后，涡轮增压器仍然超过预定限制，则系统调用对发动机的加油降额以保护涡轮增压器。如果没有超过限制，则系统操作涡轮增压器以向发动机提供期望的空气质量流，以便最大限度地发动机性能。
