The exhaust pressure signal from such a pump can be practically acquired with a standard transducer, and described with an auto-regressive (AR) model. A novel discrete-time SMO scheme has been designed to estimate AR model coefficients based on a short data set sampled from the exhaust pressure signal, and a nominal set of model coefficients estimated from fault-free data. Vacuum pumps' exhausts are at risk of blockage due to solid deposits of process chemicals. The results demonstrate that the reduction in free volume of the silencer can be detected by monitoring the injection signal of the SMO. The magnitude of the injection signal is related to the difference in location between the poles of the nominal AR model and those of the estimated model","PeriodicalId":146618,"journal":{"name":"International Workshop on Variable Structure Systems, 2006.

Second order sliding mode techniques for single-input single-output (SISO) systems show, with respect to standard sliding mode control, the same properties of robustness and precision, feature a higher order accuracy and can be exploited to eliminate the chattering effect. The application of second order sliding mode control to MIMO nonlinear systems is a challenging matter. The presented MIMO control method applies to a quite large class of nonlinear processes affected by uncertainties of general nature; the control design is simple; the conditions of existence on the controllers are weak.

A new sliding mode neurocontroller is suggested to solve this problem. The designing of this controller includes the construction of online state estimates and the corresponding tracking control based on sliding mode approach using obtained state estimates. We apply a special sliding mode technique during the \"offline training\" to estimate the right-hand side of the given dynamics in finite-time and then to use these estimates for the best (in LQ-sense) nominal weights selection in the designed neuro observer. A switching (sign) type term is incorporated in to the observer structure to correct the current state estimates using only available and on-line measurable output data supplied with a new learning procedure with a relay term.

Based on the use of a switching surface, which performs sliding mode with desired tracking in steady state, a centered pulse ZAD algorithm is designed to yield fixed-frequency pulse width modulation (PWM). A power inverter has been simulated by means of PSIM software, which allows including realistic (i.e. resistive losses, dead time of switches, quantification and sampling and so on) effects in the simulation process. Additionally, the control algorithm has been programmed in C code, which could be used, with slight modifications, to programme a digital controller (microprocessor, DSP, etc.). The simulation results from generating triangular and sinusoidal waveforms show the fulfilment of the specifications. Namely, zero error tracking and robustness with respect to different loads: resistive load, nonlinear load, time-variable load and open circuit operation","PeriodicalId":146618,"journal":{"name":"International Workshop on Variable Structure Systems, 2006.
