Patent number: 11271502Abstract: The present invention discloses a control system for an electric machine. In order to control the electric machine, predetermined frequency components are extracted from manipulated variables or measurement variables of the electric machine and are multiplied by a previously calculated control matrix. The control matrix can be calculated in advance here. Different control matrices can be formed in advance for different applications. As a result, simple efficient and robust control of the electric machine is possible, in particular for optimising and minimising harmonics.Type: GrantFiled: March 2, 2018Date of Patent: March 8, 2022Assignee: Robert Bosch GmbHInventors: Maximilian Manderla, Florian Malchow, Michele Hirsch

Patent number: 11271470Abstract: The invention relates to the controlling of a multi-phase rectifier for adapting the temperature distribution in the rectifier. According to the invention, the phase currents in the individual phases are adjusted on the output-side of the rectifier with a different amplitude. Correspondingly, the respective half bridges in the rectifier are loaded to a differing degree. In this way, an uneven temperature distribution can be compensated in the rectifier. Alternatively, an uneven temperature distribution can also be adjusted in the rectifier in a targeted manner, in order to take further parameters into account.Type: GrantFiled: April 25, 2018Date of Patent: March 8, 2022Assignee: Robert Bosch GmbHInventors: Michele Hirsch, Florian Malchow, Tino Merkel

Patent number: 11108346Abstract: The method for detecting a position error of an electronically commutated actuator drive between an assumed position and an actual position of the actuator drive includes performing a position control procedure for the position of the actuator drive. The method further includes providing data with regard to the assumed position of the actuator drive. The method further includes forming an electric space vector value to generate a component of a stator magnetic field that extends parallel with a direction of an exciter magnetic field that prevails in the case of the assumed position of the actuator drive. The method further includes detecting whether a movement of the actuator drive has occurred as a result of generating the component of the exciter magnetic field.Type: GrantFiled: August 5, 2014Date of Patent: August 31, 2021Assignee: Robert Bosch GmbHInventors: Florian Malchow, Udo Sieber, Dieter Schwarzmann, Tobias Mauk, Andreas Ortseifen

Patent number: 10972039Abstract: The invention provides a device (10) and a method for controlling an electric machine (1). The method comprises the steps of: providing (S01) a desired torque value (54) for a torque to be exerted by the electric machine (1); determining (S02) a fault signal (51) which indicates a fault state of the electric machine (1); determining (S03) a current rotor angle value (56) of the electric machine (1); determining (S04) a fault state operating point (62; 62?) on the basis of the desired torque value (54) provided, the determined fault signal (51) and the determined current rotor angle value (56); and shifting or moving (S05) an operating point, at which the electric machine (1) is operated, from a normal state operating point (61) to the determined fault state operating point (62; 62?).Type: GrantFiled: December 20, 2016Date of Patent: April 6, 2021Assignee: Robert Bosch GmbHInventors: Eckart Mayer-John, Florian Malchow, Stefan Schaut

Patent number: 10924034Abstract: The invention relates to the controlling of a rectifier with multiple electrical phases. In at least one electrical phase, the duty cycles are merged with one another in two consecutive cycles of the pulse-width modulated controlling, i.e. in a first PWM-pulse, the duty cycle is shifted to the end of the PWM-pulse, and in a subsequent PWM-pulse, the duty cycle is shifted to the start of the PWM-pulse. As a result, there must be no switching process between two consecutive PWM-pulses. In this way, the switching losses and consequently the rise in temperature of the rectifier can be minimised.Type: GrantFiled: April 25, 2018Date of Patent: February 16, 2021Assignee: Robert Bosch GmbHInventors: Florian Malchow, Michele Hirsch, Tino Merkel

Patent number: 10897189Abstract: The present invention relates to a variation of the clock frequency for pulse-width-modulated actuation of an electrical converter. In this context, the clock frequency can be specifically lowered in an angle range of an electrical period of an AC current to be output. The specific lowering of the clock frequency during predetermined angle ranges of the electrical period allows the load on the switching elements in the converter to be adjusted. As a result, it is possible, by way of example, to adjust the temperature distribution or thermal load in the converter.Type: GrantFiled: April 25, 2018Date of Patent: January 19, 2021Assignee: Robert Bosch GmbHInventors: Florian Malchow, Michele Hirsch, Tino Merkel

Publication number: 20200099326Abstract: The invention relates to the regulation of an electric machine, wherein an interference variable is compensated for and simultaneously a target value is set. In the process, two mutually independent control loops are provided. A first control loop is used to compensate for the interference variable, and a second control loop is used to set a specified target value. When the specified target value is being regulated, the control loop is decoupled from the interference variable compensation process. In this manner, a modular independent regulation can be achieved for the target value and the interference variable compensation process.Type: ApplicationFiled: February 14, 2018Publication date: March 26, 2020Inventors: Florian Malchow, Maximilian Manderla
