In this article, the innuence of uncertainty on weights and biases of neural networks on the input/output behavior is investigated. Moreover, a uncertainty description of uncertain neural networks is derived and an appropriate norm bound of the model uncertainty , which is needed for robust control design, is derived. Finally, feedback linearization is used in order to fully incorporate neural ...
Most industrial processes are nonlinear systems, the control method applied consisting of a linear controller designed for the linear approximation of the nonlinear system around an operating point. However, even though the design of a linear controller is rather straightforward, the result may prove to be unsatisfactorily when applied to the nonlinear system. The natural consequence is to use ...
Underactuated biped robots control is one of the interesting topics in robotics. The main difficulties are its highly nonlinear dynamics, open-loop instability, and discrete event at the end of the gait. One of the methods to control underactuated systems is the partial feedback linearization, but it is not robust against uncertainties and disturbances that restrict its performance to control b...
Nonlinear Design of 3-axes Autopilot for Short Range Skid-to-turn Surface-to-surface Homing Missiles
Traditionally, missile autopilots have been designed using linear control approaches with gain scheduling. Autopilot design is typically carried out in the frequency domain and the plant is linearized around various operating points on the trajectory. Moreover, three single axis autopilots are usually designed without considering the interaction among the motion axes, i.e., the autopilots in ea...
Input–output (I–O) feedback linearization suffers from a number of restrictions which have limited its use in model-based predictive control. Some of these restrictions do not apply to the case of bilinear systems, but problems with input constraints and unstable zero dynamics persist. The present note overcomes these difficulties by means of an interpolation strategy. Involved in this interpol...
− This paper proposes the use of feedback linearization for the characterization of thermoresistive sensors and for the control of measurement systems based on thermoresistive sensors kept at constant temperature. Two important benefits brought by feedback linearization are: regarding sensor characterization, it allows the determination of static and dynamic parameters by a single experimental ...
Large payloads hoisted by overhead cranes exhibit the same behavior as that of a double-pendulum. Changes in hoisting cable length during payload transfer maneuvers give rise to time-dependent system frequencies rendering input-shaped commands ineffective. In this paper, frequency-modulation input-shaping strategy enables simultaneous hoist and travel using single-mode is presented. This utiliz...
a fault-tolerant control (ftc) methodology has been presented for nonlinear processes being imposed by control input constraints. the proposed methodology uses a combination of feedback linearization and model predictive control (flmpc) schemes. the resulting constraints in the transformed process will be dependent on the actual evolving states, making their incorporation in the design context ...
This paper deals with the problem of angle-of-attack modulation with the aim of enhancing transient performance of entry guidance during bank reversals, while compensating adverse effects of fast time-varying transient disturbances. An extended single-input/single-output system is developed in the velocity domain by means of a dynamic extension technique, and explicitly captures the trajectory ...
