The Inner Mongolia Autonomous Region has abundant solar energy and electric power resources. Due to the long distance between cities, the transmission lines are too long, which leads to difficulties in line inspection. To overcome the problem of line inspection, a field patrol car using solar energy is studied in this paper, the energy system of which can complete the charge and discharge independently and then realize the inspection task.Revolving around the energy autonomy of solar-energy field inspection vehicle, this paper first selects the appropriate components and builds the energy-autonomy inspection system of the patrol car, according to its design requirements. Then the solar tracking algorithm and MPPT control algorithm are used to improve the conversion rate of solar panels, so that the fast charging can be realized. Finally, the hardware and software of the solar controller are designed, and the corresponding functions are debugged.

Wheeled mobile robots have a wide range of applications in aerospace, military, industry, medical services, and even entertainment. It is simple in design and easy in fabrication and is widely studied by scholars at home and abroad. However, the path-tracking problem of wheeled mobile robots has also been a key problem inhibiting their development. In this design, the kinematic model of the robot is constructed by using P and feedforward, and a double closed-loop P and feedforward control system is designed. After a trial-and-error method, the appropriate control parameters are obtained. The simul ink function in MATLAB is used to simulate and verify the path-following ability of the method.

In this design, a VTOL aircraft system is used as the controlled object. Aiming at the trajectory tracking problem of its position and attitude output, a trajectory tracking control method based on double closed-loop PD control is adopted to design. The trajectory tracking system of VTOL aircraft is decomposed into a track tracking subsystem and a roll tracking subsystem. At the same time, a double closed-loop PD control structure based on position outer loop and attitude inner loop is constructed, and a PD controller based on feedforward compensation is designed. The pole assignment method is used to set and select PD parameters. The stability of the double closed-loop system is ensured by the engineering method of making the reaction speed of the inner loop greater than that of the outer loop. Then, MATLAB software is used to simulate whether the control system can track the given trajectory. Simulation results show that this method simplifies the design process of the control system and makes certain that VTOL aircraft can track arbitrary trajectory outputs with three state outputs as soon as possible, thus meeting the needs of underactuated VTOL aircraft for arbitrary trajectory tracking.

The Inner Mongolia has abundant solar energy and electricity resources. Because of the long distance between cities, transmission lines are too long, making it difficult to check lines. In order to solve the problems existing in the inspection work, this paper studies a kind of outdoor inspection vehicle using solar energy, the energy system of the inspection vehicle can independently complete the charge and discharge, so as to realize the inspection task. This paper focuses on the energy autonomy of the on-site inspection vehicle for solar energy. According to the design requirements of the inspection vehicle, appropriate parts are selected to build an energy autonomy inspection system for the inspection vehicle. Then the solar tracking algorithm and maximum power tracking control algorithm are used to improve the conversion rate of solar panels and achieve fast charging. Finally, the hardware and software of the solar controller are designed, and the corresponding functions are debugged.
