“…The fundamentals of motor sizing are well-known and beyond the scope of this thesis, so that only a rough overview is given in the following. The reader is referred to the relevant literature, e. g., [165]. Only the continuous and intermittent load ratings of the servo motors are discussed with special regard to thermal capabilities.…”

The autonomous robotic complexes allow solving a wide range of scientific, civil and military tasks. In order to work correctly, these complexes have to include a number of heterogeneous functional systems in its composition. The implementation of these systems requires a significant number of separate modules and devices that makes it relevant to develop new approaches to the organization of control systems that correspond to complexity of the object. This work is aimed at the development of distributed control systems for robotic complexes. This paper presents the architecture of the distributed and centralized control system, also the generalized modules structure for its realization. The proposed architecture consists of three levels and it can be used for autonomous robotic complexes and unmanned vehicles for different applications. The generalized structure of the modules allows developing typical circuit solutions for sensor and actuating modules of the system. The control system of the mobile autonomous robotic platform for general purposes was developed and realized based on the proposed architecture. In this robotic complex the CANbus is used as internal system communication bus, through that the data exchange is accomplished between modules of devices level and high-level controller. The devices level of the robotic platform includes fourteen modules, including the modules of the motor-wheels control, in the example of that the application of the proposed generalized structure was considered.

“…The full torque is available up to the so-called corner speed. Above this threshold, in the field-weakening range, the motor torque decreases with 1⁄ ( = motor speed; see Figure 5) [27]. In the field-weakening range, the turning rotor with its permanent magnets-a permanent-magnet (PM) motor is assumed for reasons explained in Section 3.3induces a voltage that counteracts the primary field of the stator and can no longer be fully compensated by the voltage supply of the frequency inverter.…”

The further development of electric mobility requires major scientific efforts to obtain reliable data for vehicle and drive development. Practical experience has repeatedly shown that vehicle data sheets do not contain realistic consumption and range figures. Since the fear of low range is a significant obstacle to the acceptance of electric mobility, a reliable database can provide developers with additional insights and create confidence among vehicle users. This study presents a detailed, yet easy-to-implement and modular physical model for both passenger and commercial battery electric vehicles. The model takes consumption-relevant parameters, such as seasonal influences, terrain character, and driving behavior, into account. Without any a posteriori parameter adjustments, an excellent agreement with known field data and other experimental observations is achieved. This validation conveys much credibility to model predictions regarding the real-world impact on energy consumption and cruising range in standardized driving cycles. Some of the conclusions, almost impossible to obtain experimentally, are that winter conditions and a hilly terrain each reduce the range by 7–9%, and aggressive driving reduces the range by up to 20%. The quantitative results also reveal the important contributions of recuperation and rolling resistance towards the overall energy budget.

This paper discusses nonlinear proportional-integral (PI) current control with anti-windup of reluctance synchronous machines (RSMs) for which the flux linkage maps are known. The nonlinear controller design is based on the tuning rule "Magnitude Optimum criterion" [1]. Due to the nonlinear flux linkage, the current dynamics of RSMs are highly nonlinear and, so, the parameters of the PI controllers and the disturbance compensation feedforward control must be adjusted online (e.g., for each sampling instant). The theoretical results are illustrated and validated by simulation and measurement results.
