A Microcomputer-Based Simulator for Digital Control Systems

A microcomputer-based simulator for digital control systems is proposed. The proposed simulator is a hybrid system in which the plant is simulated by conventional method of analog computers and other parts of the system including generation of input signal is performed digitally, using a Z-80 based microcomputer. To overcome the difficulty of programming in assembly language, and at the same ti...

Digital Implementation of Adaptive Control Algorithms for MEMS Gyroscopes

In this report, we present a hybrid discrete/ continuous time version of the observer-based adaptive control system for MEMS gyroscopes developed in [8], which can be readily implemented using digital processors. The control algorithm considered in this report is not fully a discrete time controller, since only the feedback control, parameter adaptation algorithms and feedforward control law ar...

Genetic Algorithms for Digital

Recursive digital lters are potentially less computationally expensive than their non-recursive counterparts. However, algorithms for adjusting the coeecients of recursive lters may produce biased or sub-optimal estimates of the optimal coeecent values. In addition, recursive lters may become unstable if the adaptive algorithm updates a feedback coeecient so that one of the poles remains outsid...

Assessment of the conventional control algorithms and proposing a modified displacement feedback control for performance-based design of structures

An enhanced displacement feedback structural control procedure is presented for performance-based design in this paper. At first, a comparative study is implemented assessing three most common active control algorithms including state, acceleration, and displacement feedback controls. The advantage of the displacement feedback algorithm for active control of structures against earthquakes is de...
