the colorado beetle, leptinotarsa decemlineata (say), is the major defoliating and exotic insect pest of potato plants and has caused serious problems in the east azerbaijan and ardabil regions of iran since emerging in the absence of natural native enemies. in the development of a suitable control strategy based on integrated pest management, it is important to recognize control methods that d...

this paper addresses the problem of the fractional sliding mode control (fsmc) for a mems optical switch. the proposed scheme utilizes a fractional sliding surface to describe dynamic behavior of the system in the sliding mode stage. after a comparison with the classical integer-order counterpart, it is seen that the control system with the proposed sliding surface displays better transient per...

rice is the world's most important food crop. to decrease the damage of  rice pests, development of insect pest management strategies in rice is necessary. biennial results for determination of a suitable method to control striped stem borer in rice showed that integration of two methods of control (biological and mechanical) is a feasible effort to reduce stem borer infestation. to assure...

This paper presents a theoretical framework for the dynamics and control of underactuated mechanical systems, defined as systems with fewer inputs than degrees of freedom. Control system formulation of underactuated mechanical systems is addressed and a class of underactuated systems characterized by nonintegrable dynamics relations is identified. Controllability and stabilizability results are...

in this paper, a robust pid control scheme is proposed for micro-electro-mechanical-systems(mems) optical switches. the proposed approach is designed in a way which solves twochallenging and important problems. the first one is successful reference tracking and the second ismitigating the system nonlinearities. the overall system composed of nonlinear mems dynamicsand the pid controller is prov...
