This approach, originallydesigned for systems with a Multiple-Input Single-Output(MISO) structure, is carried out by three main steps whichare data clustering, parameters vectors estimation and regionscomputing. Data clustering is the most important stepbecause the two other steps depend on the results given bythe used clustering algorithm. In case of MIMO PWA systems,we should cluster matrices of parametres which areconsidered high dimensionnal data. However, most of theconventional clustering algorithms do not work well in termsof effectiveness and efficiency since the similarity assessmentwhich is based on the distances between objects is fruitlessin high dimension space. Therefore, we propose an extensionof the DBSCAN (Density Based Spatial Clusteringof Applications with Noise) clustering approach for the identificationof MIMO PWA systems. The simulation resultspresented in this paper prouve the performance of the suggestedapproach. An application of the proposed approachto an industrial robot manipulator is also presented in orderto validate the simulation results.

Firstly, considering the nonlinear characteristics of the spring-damping in the guide shoes, the horizontal vibration dynamic model of the elevator car system is established. Then, the guide rail excitation and the linear and nonlinear disturbances of the car are summarized into the total disturbances of the car system, which can be estimated by the designed extended state observer. On this basis, a sliding mode active disturbance rejection (SADR) control is presented, which makes the anti-vibration and anti-disturbance control of the car system highly robust. For the chattering problem caused by sliding mode control, the fuzzy control method is designed to eliminate it, and the fuzzy sliding mode active disturbance rejection (FSADR) control for the horizontal vibration of the car system is further realized. Finally, MATLAB/Simulink is utilized for simulation tests. The simulation results show that, compared with ADR and SMADR, the root mean square value, maximum value and A95 peak value of horizontal vibration acceleration through FSADR are significantly reduced. Therefore, the FSARC control method designed in this paper can effectively suppress the horizontal vibration generated during the operation of high-speed elevators.

The service capacity management workflows connect multiple instances of online reservation and front-office customer registration processes (booking, check-in taxation, check-out invoicing according to the back-office strategy) with a combination of marketing- and operations-oriented back-office processes that: a) best match capacity and demand for quality services, and b) optimize the staffing levels and personnel workshift schedules. These workflows with many operations and complex timing are automated with the Robotic Process Automation (RPA) technology that uses AI techniques for seasonality prediction of confirmed service demand. A case study of optimal hotel staff assignment with RPA using the Blue Prism scheduler is included, and the gains of using RPA solutions are presented.

To solve this problem, parameterized reduced-dimension trajectory planning and tracking control are carried out. The plant is reduced in dimension by using the differential flatness (DF) method, wherein the state and control variables are represented directly through the flat output (FO). Combined with the pseudospectral method (PSM) wherein multiple constraints are taken into account, the FO is parameterized by using the polynomial functions, and the trajectory planning in the FO space is transformed into a parameter planning problem. By doing so, it can reduce the degree of freedoms to be optimized. For the high-order terms and various disturbances in the FO, the extended state observer is used for estimation and compensation. Both numerical simulation and hardware experiments are performed to demonstrate the feasibility and efficiency of the proposed method.

Based on this algorithm, a quality prewarning system is developed on LabVIEW software. First, the GM (1,1) gray prediction model is established with the number of qualified products in the test batch as the original sequence, and then a nonlinear iterative parameter is proposed to improve the WOA. The improved WOA is used to optimize the background value sequence in the GM (1,1) gray prediction model, to obtain the optimal prediction algorithm. Then, on the LabVIEW software platform, the simulation of the GM (1,1) gray prediction model, the algorithm combining WOA and GM (1,1) and the algorithm combining the improved WOA and GM (1,1) are carried out for fifty groups of original data series. Taking one group of simulation data results as an example, the relative error of the prediction value of the algorithm combining the improved WOA and GM (1,1) is 0.0004%, which is better than 0.0112% of the algorithm combining the WOA and GM (1,1) and 1.5429% of the GM (1,1) gray prediction model. Finally, the quality prewarning system of the supercapacitor module is developed by using LabVIEW software, which provides a more accurate quality prewarning function for the test process of the supercapacitor module.
