In future the dynamical system which is highly nonlinear & unstructured would be required a more precise control system. Various issues for the stabilization of the plant with parametric uncertainties and unpredictable environments remain unsolved. Sliding mode controller (SMC) is one of the nonlinear robust controller that can solve these issues. In this paper the robustness property of the PID...
We describe and test a non-linear control algorithm inspired by the behavior of motor neurons in humans and other animals during extremely fast saccadic eye movements. The algorithm is implemented on a robotic eye, which includes a stiff camera cable, similar to the optic nerve, which adds a complicated non-linear stiffness to the plant. For high speed movement, our “pulse-step” controller operates...
This paper presents the detailed account on the control design of a buck converter driven dc motor. Proportional-integral (PI) and proportional-integral-type fuzzy logic controller (PI-type FLC) are the techniques proposed in this investigation to control the speed of a dc motor. The dynamic system composed from converter/motor is considered in this investigation and derived in the state-space and...
Almost all of control methods proposed so far have been designed in the continuous-time domain. Actual systems, however, have been implemented in the discrete-time domain since MCU and/or microprocessors have been used for the control system, that is, the overall system turned to be a sampled-data system. In this case, the ultimate error cannot converge to zero in the actual system even though the...
