Definitions
- the invention relates to a method for controlling a ship propulsion system with a surface propeller.
- trim position In fast ships surface propellers are often used. This can be changed in the submerged depth as well as to port or starboard to control the ship.
- the immersion depth of the surface propeller is referred to as the trim position.
- a trim position of + 100% corresponds to a maximum replacement position and a trim position of -100% of a maximum immersion depth of the propeller.
- a skipper sets the subjectively best trim position via an actuator. However, this leads to an additional load of the ship's master in addition to his nautical duties. In dynamic processes, he often lacks the evaluation criteria for the best trim position.
- WO 2004/020281 Al proposes a method for automatically adjusting a surface propeller depending on the current operating state of the ship.
- the current operating state in turn becomes from the ship speed, a steering angle, the position of a throttle lever and characteristics of the internal combustion engine derived.
- a specific embodiment is not apparent from this reference.
- a method and a device for load control of a marine propulsion system with a variable pitch propeller which comprises a speed control circuit for speed control of the internal combustion engine and a system controller for controlling the variable pitch propeller.
- a SoIl speed is calculated as a reference variable for the speed control loop on a first map.
- a target wing pitch is then converted via the plant controller into a control variable for the variable pitch propeller.
- a power reserve of the internal combustion engine, a speed deviation and a speed gradient in terms of increasing or decreasing the wing pitch are taken into account.
- a large power request change causes a direct, same-direction change in the SoIl speed and the target wing pitch.
- the speed control loop Due to the system, the speed control loop has a large step response time.
- a change in the manipulated variable, for example the injection quantity therefore causes a time-delayed change in the actual rotational speed and the variables derived therefrom.
- the desired wing pitch is quickly converted by the controller into a control variable for the variable pitch propeller. Since the variable pitch propeller with the variable hydraulic has a large time constant, this behavior is mitigated.
- the method known from DE 195 15 481 A1 can not be mirror-inverted on a ship propulsion system with a surface propeller.
- the method consists in that the desired power is interpreted as a desired speed and from the target speed and the actual speed of the internal combustion engine, a speed control deviation is calculated. From the speed control deviation, in turn, a Einspitzmenge for speed control of the internal combustion engine is set and calculated an effective speed via a speed controller.
- the effective speed is the reference variable of the system controller, which regulates the trim position of the surface propeller. In the regulation of the trim position, the power reserve of the internal combustion engine is taken into account.
- the method according to the invention thus differs from the previously described prior art in that the reference variable for the system controller is not directly derived from the Performance is derived, but from the effective speed. Another difference is that the trim position of the surface propeller is controlled.
- the effective speed is calculated via a map in which preferably a staircase function is shown. Temporarily short changes in the actual speed, for example, due to the swell, cause no change in the effective speed.
- the effective speed is thus a robust reference variable.
- the effective speed is corrected by engine-internal parameters, such as the boost pressure of an exhaust gas turbocharger.
- a first adjustment angle is determined via a trim preset with a plurality of selection maps.
- the selection of a map is carried out as a function of the number of coupled drive shafts and the thrust direction of the transmission, such as turning or reversing.
- the maps cause an improved adaptation of the drive system to the external conditions. For example, when reversing, the trim position is changed in the direction of -100%, so that the water moved by the surface propeller flows under the stern of the ship. This considerably reduces the flow resistance.
- the first adjustment angle in turn is processed together with the power reserve in a load control, which generates the reference variable, here: second adjustment angle, for the trim controller and a first adjustment rate.
- the trim controller then defines the trim position based on the second adjustment angle, the actual trim position, and the first adjustment rate. More generally, the advantages of the invention are that the engine remains in the tested load range for significant performance-desired changes and the automatic control of the trim position represents a corresponding comfort for the skipper.
- the maps are designed so that an economical and effective operating state is set automatically at each operating point.

- a map 15 shown is a step function, an effective speed nEFF.
- the speed control deviation dn is filtered via the step function, ie the effective speed nEFF is robust against small deviations.
- the effective speed nEFF is corrected by means of a factor E which identifies engine-internal parameters, for example the boost pressure of an exhaust-gas turbocharger.
- a first adjustment angle Phil is set via the trim setting 9.
- the trim specification 9 contains a plurality of characteristic diagrams, which are designated in FIG. 1 by KF1, KF2 and KF3.

- the first adjustment angle Phil, the power reserve PRES and the actual trim position POS (IST) are the input variables of the load control 10.
- a first adjustment rate VSR1 and a second adjustment angle Phi2 are determined via the load control 10.
