In the complex control system, the generalized predictive control has the ability of nonlinear representation as usual. In order to improve the performance of roll control of ROV, a method based on generalized predictive control was proposed to restrain the overshoot and fluctuation caused by changing too fast of roll angle in this paper. When applying linear generalized prediction algorithm, the dynamic model is firstly used to describe the nonlinear dynamic process of MC-ROV and then it is equivalent to a time-varying linear system. In order to avoid the inverse matrix of generalized predictive control optimization, a direct generalized predictive algorithm for constrained input and output is used to decrease the amount of calculation with only one constraint. At the same time, due to the poor response and robustness of generalized prediction at the initial time, the PID algorithm is introduced. The experiment results on this ROV system demonstrate the effectiveness of the proposed approach and the satisfactory performance is achieved.","PeriodicalId":226586,"journal":{"name":"2018 33rd Youth Academic Annual Conference of Chinese Association of Automation (YAC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122852147","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The working voltage and temperature are selected as input variables, and the state of charge is used as the output variable to train the algorithm model.

The prototype machine uses four parallel rotor blades, which can produce larger thrust. For most rotors, the dynamic model is composed of the underexcited subsystem and the fully excited subsystem. The control strategy presented in this paper is to control the horizontal displacement by the angle position of the aircraft, and the control algorithm proved that the control algorithm can fully realize the stable control. But this kind of controller is very complex, so a simplified control algorithm is given, which is more suitable for real time experimental device. The experimental device mainly consists of embedded control system, inertial measurement unit, unmanned aerial vehicle and sensor. The independent hovering experiment was successful, and the airborne flight system and the unmanned aerial vehicle (UAV) were designed.","PeriodicalId":226586,"journal":{"name":"2018 33rd Youth Academic Annual Conference of Chinese Association of Automation (YAC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134623145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Firstly, the distributed control protocol for consensus of multi-agent systems is optimized for the given quadratic performance index. The proposed optimal controller depends on the Laplace matrix of the topological graph. Secondly, in order to further reduce the communication energy of the topology, but not affect the convergence speed of multi-agent systems, the topology optimization algorithm and the eigenvalue optimization method for multi-agent systems are presented, which balances the communication energy and control energy of the systems.

Also, it is a challenge for machines to recognize mature strawberries among those in different maturity. This work presents a fast recognition method for elevated mature strawberries by the approach of deep learning. It uses an Ostu algorithm to separate targets from background and then the resulted effective image areas designated by the minimum external rectangular marking method are used to train CaffeNet for automatic target recognition. For comparison, we also design a SVM classifer that uses HOG gradient direction feature and H component of the color feature of the mature strawberries. The experimental results show that the average recognition rate of mature strawberries by CaffeNet can reach 95%, higher than that by SVM by 11%.","PeriodicalId":226586,"journal":{"name":"2018 33rd Youth Academic Annual Conference of Chinese Association of Automation (YAC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130836013","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Modeling and compensation is a common approach to handle it. This paper proposes a distributed parameter Maxwell-slip (DPMS) model. It is extended from the Maxwell-slip (MS) model. The DPMS model replaces the spring-slider elements in the MS model by a sliding cell and a elastic cell with distributed parameters. The properties of the elastic cell are described by two functions, i.e. the saturation deformation function and the stiffness function. These two functions also govern the hysteresis generated by the DPMS model and only require a few parameters. An approach to identify model parameters are proposed. Experiments demonstrate the effectiveness of the DPMS model. With a linear function describing the saturation deformation function, only two parameters (the character length and a coefficient) are required and the normalized mean squire error is 1.96%. The hysteresis nonlinearity is reduced from 13.8% to 2.55% by 81.5% if it is compensated by the inverse DPMS model.","PeriodicalId":226586,"journal":{"name":"2018 33rd Youth Academic Annual Conference of Chinese Association of Automation (YAC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115871256","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
