Model-Reference Discretized PID Control and Robust Stabilization for Continuous Plants
نویسنده
چکیده
This paper deals with a designing problem of discrete-time and discrete-value (discretized) control systems based on a model-reference feedback structure. The model used in this study is assumed to be a second-order lag system that is expressed by a bilinear transformation. That type of discretized (nonlinear) control systems is presented and analyzed. The model reference feedback using a secondorder continuous-value (linear) system is equivalently transformed into a traditional PID control. The robust stability analysis and design of such nonlinear control systems is examined in a frequency domain. Numerical examples for model-reference type discretized control are provided to verify the design method.

Robust Stabilization for Discretized Control Systems on a Grid Pattern
This paper deals with the stability problem of discrete-time and discrete-value (discretized/quantized) control systems in a frequency domain. The discretized (stepwise) nonlinear characteristic on a grid pattern is partitioned into two sections: bounded and sectorial areas. First, by considering a sectorial area over a specified threshold, the robust stability condition for nonlinear discrete-...

In this paper, a synthesis method based on robust model predictive control is developed for compensation of uncertain time-delays in networked control systems with bounded disturbance. The proposed method uses linear matrix inequalities and uncertainty polytope to model uncertain time-delays and system disturbances. The continuous system with time-delay is discretized using uncertainty po...

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 کاملRobust Anti-Windup Control Design for PID Controllers–Theory and Experimental Verification
This paper addresses an approximation-based anti-windup (AW) control strategy for suppressing the windup effect caused by actuator saturation nonlinearity in proportional–integral–derivative (PID) controlled systems. The effect of actuator constraint is firstly regarded as a disturbance imported to the PID controller. The external disturbance can then be modeled by a linear differential equatio...
