Two-degree-of-freedom Controller Design for Uncertain Processes Using Input/output Linearization Control Technique
In this work, a new control method for uncertain processes is developed based on two-degree-of-freedom control structure. The setpoint tracking controller designed by input/output linearization technique is used to regulate the disturbance-free output and the disturbance rejection controller designed is designed by high-gain technique. The advantage of two-degree-of-freedom control structure is...
متن کاملMulti - input Multi - output PI Controller Design
The design of MIMO PI controller is formulated as an LQR problem. The weighting matrices of the quadratic performance index are chosen so that tuning can be done for each inputoutput channel and for tradeoff between transient response and robustness with respect to modeling error. The number of tuning parameters is the same as that of a decentralized PI controller. A d&ign example is given to d...
متن کاملDesign of Reduced Rule Multi Input Single Output Fuzzy Controller
It is a well known fact that the performance of a process controlled by a fuzzy logic controller (FLC) can be improved by increasing the number of rules present in the rule base. The rules can be increased either by increasing the number of inputs or by increasing the linguistic variables. In either case with increase in number of rules the computational time and computational memory required i...
متن کاملAdaptive Input-Output Linearization Control of pH Processes
pH control is a challenging problem due to its highly nonlinear nature. In this paper the performances of two different adaptive global linearizing controllers (GLC) are compared. Least squares technique has been used for identifying the titration curve. The first controller is a standard GLC based on material balances of each species. For implementation of this controller a nonlinear state...
متن کاملA Two-Time Scale Decentralized Model Predictive Controller Based on Input and Output Model
A decentralized model predictive controller applicable for some systems which exhibit different dynamic characteristics in different channels was presented in this paper. These systems can be regarded as combinations of a fast model and a slow model, the response speeds of which are in two-time scale. Because most practical models used for control are obtained in the form of transfer function m...
