Definitions
- the invention relates to a compensation controller for an electronic control unit for controlling the boost pressure in supercharged internal combustion engines with at least two actuators.
- the object of the present invention is to improve a controller for charge pressure control in such a way that when switching from one actuator to the other actuator, negative effects such as drops in the charge pressure, associated fluctuations in traction and jerks noticeable to the driver are avoided.
- the invention relates to a compensation controller for an electronic control unit for controlling the boost pressure in supercharged internal combustion engines, having at least two actuators which differ in terms of their route amplification or transfer behavior.
- the control unit has a correction module in such a way that at least one controller parameter is smoothed in a defined transition range and the integrative component (e.g. the I component of a PI or PID controller) in a defined transition range with a ratio or the difference between the system gains corresponding correction value is transferred.
- the integrative component e.g. the I component of a PI or PID controller
- the smoothing of the controller parameters preferably takes place in a defined transition range and the integrative component is corrected at an initialization time when the control is transferred from the first actuator to the second actuator with the first actuator fully open.
- the transition area therefore begins at an initialization time when the control transfers from the first actuator with a first system gain (in particular after the first actuator has reached the fully open position) to the second actuator with a second system gain that differs from the first.
- the invention is based on the following considerations:
- multiple actuators are used to achieve a target variable. This is the case, for example, when a number of drive units are used simultaneously in a vehicle in order to meet the driver's request. Further examples can be found in the boost pressure control of supercharged combustion engines and here in particular in variants with multi-stage supercharging.
- an exhaust gas turbocharger with variably adjustable turbine geometry also called VTG for short
- a bypass flap exhaust gas control flap, also called RK for short
- HP high-pressure stage
- LP low-pressure stage
- One target variable (e.g. target boost pressure) is then set with a common control system that uses a number of actuators. All but one of the actuators are often controlled, and regulation is accomplished with a single actuator.
- a compensation control must be added to compensate for model errors, disturbances, changes in the system due to aging, etc. In many cases this compensation control is a simple PI or PID controller.
- the compensation controller is designed as aggressively as possible. Different parameterizations of the compensation control are used for the different actuators, as a result of which there are abrupt changes in the output of the compensation controller when there is a transition from one actuator to the other actuator. In the worst case, the control is then carried out at least briefly on the first actuator and then the second actuator is controlled again.
- the parameterization of the compensation control is smoothed before, after or before and after the transition from one actuator to the other actuator, in particular in a defined transition range, so that there is no longer a sudden change in the output of the compensation controller.
- the integral part in the compensation controller is divided so that on the one hand the transition to the other actuator is retained and on the other hand the remaining, integral part is scaled with the different gains or set to zero.
- At least one controller parameter is smoothed out in a defined transition range in order to prevent abrupt changes in the correction value.
- the I component is Corrected the ratio of the (different) track gains.
- This correction value can be taken, for example, from a characteristic curve or a table that is empirical can be determined and stored in the control unit. However, it can also be in the form of a factor in the control unit.
- control unit therefore contains, in particular through appropriate software programming, a compensation controller with a correction module for adapting the controller parameters and scaling when transferring the integrative component to the difference in system gain when transferring control from one actuator to another actuator.
- the invention can be used particularly advantageously in a first case when the control is transferred from the VTG at the HD stage in a supercharged biturbocharger internal combustion engine (e.g. diesel engine) to the control valve (bypass valve at the HD stage) and vice versa. Furthermore, the invention can also be used in a second case when the control is transferred from the control flap on the HP stage to the VTG on the LP stage in a supercharged internal combustion engine with a rigid HP stage in two-stage supercharging operation and vice versa.
- a supercharged biturbocharger internal combustion engine e.g. diesel engine
- the invention can also be used in a second case when the control is transferred from the control flap on the HP stage to the VTG on the LP stage in a supercharged internal combustion engine with a rigid HP stage in two-stage supercharging operation and vice versa.
- FIG. 2 shows an enlargement of the control unit with a correction module according to the invention
- Fig. 1 shows a section of essential components of a double-charged diesel engine D as an example of an internal combustion engine with a first turbocharger (including a first actuator 1) and with an exhaust gas bypass control valve (including a second actuator 2) in a high-pressure path HD level and with a second turbocharger 3 in a low-pressure path ND level.
- At least the turbocharger in the high-pressure path has a variably adjustable turbine geometry (VTG actuator 1).
- the control flap has a variably adjustable valve (RK actuator 2).
- the internal combustion engine D has a pressure sensor P1 on the input side for detecting the high-pressure charge pressure p_HD_actual and optionally a pressure sensor P2 for detecting the precompression p_ND_actual.
- the invention is described below, as mentioned above, for a first case when the control is transferred from the VTG to the HD stage, i.e. from the first (VTG) actuator 1, to the control flap, i.e. the second (RK) actuator 2 explained.
- the internal combustion engine D and, in particular, also the charge pressure is regulated by an electronic control unit 4 .
- the current high-pressure boost pressure p_HD_actual is the input signal of the electronic control unit 4.
- the target high-pressure boost pressure p_HD_soll is also specified as a command variable of a controller, for example a model-based boost pressure controller supplemented by a PI controller for compensation.
- control unit 4 contains a controller, in particular a compensation controller according to the invention with a correction module 5.
- exemplary output signals of the control unit 4 are the control signals for the first actuator 1 (VTG) and the second actuator 2 (RK).
- the configuration (in particular programming) of the correction module 5 is explained in more detail in connection with FIG. 3 .
- the VTG actuator 1 and the RK actuator 2 have different track gains. These are shown schematically as an example in Fig. 3:
- controller parameters to be smoothed and the correction of the I component are considered with reference to FIG.
- a position change Ar_T of 40% is required with the first actuator 1 and only a position change Ar_B of 8.2% with the second actuator 2 .
- This difference in the system amplification (amplification factors through AA/Ar_T or AA/Ar_B) is represented by forming the ratio of the amplification factors k_T and k_B and as a correction value for the I component i_T of the first actuator 1 to the I component i_B of the second actuator 2 Are defined.
- the invention can also be applied analogously, for example, to the pressure control in the LP stage.
