In this study, an active control algorithm is developed in order to control a particular mode of a shear building. The location of the actuator is considered at the first floor level for an easy application of the control force. In order to achieve the desired control, the sliding surface is designed in such a way that the effect of a particular mode of the structure at an ideal sliding is nullified. | Journal of Automation and Control Engineering Vol. 4, No. 5, October 2016 Development of a New Algorithm to Control Excitation of Particular Mode of a Building Sanjukta Chakraborty and Samit Ray Chaudhuri Department of Civil Engineering, Indian Institute of Technology, Kanpur, India Email: {sanjukta, samitrc}@ review of such algorithms can be found in [3]. Apart from the existing conventional algorithms, researchers have developed new algorithms as well for specific problems by modifying the conventional one. To name a few, Feng, Shinozuka and Fujii [4], [5], Fujii and Feng [6], [7] used instantaneous optimal control and bang-bang control algorithm; Yang, Wu, Reinhorn, and Riley [8] used a well-known sliding mode control; Amini and Vahdani [9] combined three control algorithms such as probabilistic optimal control, fuzzy logic-based control and optimal control theory; Pnevmatikos and Gantes [10] proposed a modified pole placement algorithm; Cetin, Zergeroglu, Sivrioglu, and Yuksek [11] developed a nonlinear adaptive controller for a magneto-rheological MR damper through Lyapunov-based techniques; Kim [2] used skyhook control and Fuzzy logic-based control; Ozbulut Bitaraf and Hurlebaus [12] used an Adaptive Fuzzy Neural Controller (AFNC) and Simple Adaptive Control (SAC) to compare with LQG control algorithm; Park and Park [13] proposed a minmax algorithm. It may be noted that most of these studies deal with the response reduction of base isolated structures. From literature, the idea of a sliding mode control is first evolved in Russia in the early , it become popular in mid 1970s from the work done by Utkin [14].The concept of sliding mode control have widely applied in the area of flight control, space system and robots, control of electric motors or many other adaptive schemes. However, in case of civil structure like building, bridges the application is limited. The sliding mode controlled system is often termed as the variable .
