Robust 2DOF PID Controller Design of Time-delay Sysytems Based on Evolutionary Computation
نویسنده
چکیده
This paper presents a new evolutionary computing method for the design of robust PID controller with two degrees of freedom (2DOF PID controller). Since the objective plants have a time-delay element and parametric uncertainties, the design problem is formulated as a multi-objective minimax optimization problem. Therefore the high-performed optimization method is required. The proposed evolutionary computing method is to generate a set of pareto-optimal solution that is properly distributed in the trade-off surface generated by multi-objective functions. Numerical examples show the effectiveness of the proposed approach. Key-Words: Evorutionary computing, Dividing strategy, PID controller, Time-delay systems, Robustness

Robust Lyapunov-based Control of MEMS Optical Switches
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 two challenging and important problems. The first one is successful reference tracking and the second is mitigating the system nonlinearities. The overall system composed of nonlinear MEMS dynamics and the PID controller is ...

متن کاملDesign of a Data-oriented 2DOF Nonlinear Controller
This study considers about the 2 degree-offreedom (2DOF) nonlinear controller. The proportionalintegral-derivative (PID) controllers have been widely used in many process systems. There are broadly-divided two design methods. One is a model-based controller design that tunes PID parameters based on a system model. The other is a dataoriented controller design that tunes these parameters by usin...

متن کاملSCA based Fractional-order PID Controller Considering Delayed EV Aggregators
The EVs battery has the ability to enhance the balance between the load demand and power generation units. The EV aggregators to manage the random behaviour of EV owners and increasing EVs participation in the ancillary services market are employed. The presence of aggregators could lead to time-varying delay in load frequency control (LFC) schemes. The effects of these delays must be considere...
