Fractional PID Controller Design Based on Minimizing Performance indices

PID Controller Design Based on Minimizing Generalized Output Errors

PID control systems have been widely employed in industrial processes. Recently, some data-oriented PID control systems have been proposed because it is difficult to adjust a set of suitable PID gains. In this paper, one of data-oriented PID control schemes, which is designed by using the generalized output errors, is proposed. The generalized output is defined from a PID control law. Moreover,...

SCA 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...

A Novel Fractional Order Fuzzy PID Controller and Its Optimal Time Domain Tuning Based on Integral Performance Indices

A novel fractional order (FO) fuzzy Proportional-Integral-Derivative (PID) controller has been proposed in this paper which works on the closed loop error and its fractional derivative as the input and has a fractional integrator in its output. The fractional order differ-integrations in the proposed fuzzy logic controller (FLC) are kept as design variables along with the input-output scaling f...

Performance Degradation Driven PID Controller Design

This paper is concerned with the design of the closed-loop control system, in order to take into account the system performance to load-disturbance and to set-point changes and its robustness to variation of the controlled process characteristics. The aim is to achieve a good balance between the multiple trade-offs. The proposed approach is complementary to the work presented by Arrieta and Vil...
