摘要： The present document discloses a control method for trajectory tracking of a dynamic system (2) having an input u(t) and having an output y(t), comprising the steps: obtaining a signal error e(t) from the difference between a reference signal u(t) and the output signal y(t); obtaining, by a controller (1,4), a control value cBN(t) determined by a black hole (BH) gravitational potential field of a black hole with mass M(t), wherein the reference signal u(t) is the black hole centre, wherein the signal error e(t) is a distance of a current position y(t) to the black hole centre u(t); wherein the output signal y(t) is a current position within a black hole Schwarzschild radius of the black hole, and where the black hole mass M(t) includes a factor of matter accretion; and inputting the control value cBN(t) into the dynamic system (2). It is further disclosed a respective controller and dynamic system (2) comprising a controller for trajectory tracking.

摘要： A storing unit stores, amongst coefficients, values of a coefficient group associated with one selected from multiple variable groups, which are obtained by dividing state variables of an evaluation function. A searching unit searches for a solution to an optimization problem by repeating update processing, which includes calculating, using the values of the coefficient group, a value change of the evaluation function responsive to changing the value of each state variable of the variable group and changing the value of one state variable thereof based on the value change and temperature. A processing unit calculates multiplicity indicating the iteration count in which the values of the variable group are maintained in a search using Markov chain Monte Carlo (MCMC), and causes, responsive to cumulated multiplicity exceeding a threshold, the searching unit to perform the update processing using the values of the coefficient group associated with a different variable group.

摘要： Disclosed is a navigation information processing method and apparatus, an electronic device, and a storage medium. The navigation information processing method includes: acquiring (S 101) motion state information of a vehicle based on an inertial device, and acquiring vehicle information of the vehicle based on a controller area network; performing (S102) a strapdown solution on the motion state information to obtain navigation information; fusing (S 103) the navigation information and the vehicle information by using a preset Kalman filter to obtain target navigation information, where an input vector of the Kalman filter is a two-dimensional vector; and navigating (S104) the vehicle based on the target navigation information. In the navigation information processing method, data collection does not need to rely on environment, and problems of unstable navigation effects caused by insufficient acquired data are solved. A Kalman filter is used to fuse navigation information and vehicle information, improving accuracy of navigation information and precision of positioning. In addition, a two-dimensional vector is used as an input vector of the Kalman filter, which has a simple filtering manner and consumes few hardware resources, reducing navigation costs.
